I am a professional knife sharpener of seven years. When I was first starting out, I thought this sharpener would be cool as it’s something you can easily carry around. Pretty quickly into sharpening I learned this is nothing more than a gimmick and good sales advertising. If you cut a knife in half and look down the spine of the knife, you would see a triangle shape, the goal in sharpening is to sharpen both edges of the knife until the triangle comes together to a super sharp point called the Apex of the edge. You could sharpen a knife for a really long time and it could look beautiful and shiny, but if you haven’t reached the Apex of the edge where the triangle fully comes to a point you’re never actually getting the edge sharp. Once you have reached the Apex of the edge where you can feel a tiny burr or piece of metal fold over to one side of the knife you work on using finer grits to refine the knife edge till you get it to a desired level of sharpness for the task it needs to perform. Some knives and cheaper steals you want to leave a slightly toothier edge so it will stay sturdier and bite into what you are cutting. Some more expensive knives or steals like S30V and high carbon you can get a lot sharper because of the quality of the metal. Brad Buckner doesn’t know much about knives it seems as stated in the video which you should if you are a sharpener selling knife sharpeners. Also Gerber knives are usually not very hard steels especially not that older kitchen knife. (Not bashing the guy who brought it). Brad doesn’t seem to know much about steel composition and in previous videos has admitted to using a work sharp knife sharpener to sharpen his knives. This is probably also why he demos his knife sharpener at gun shows and not blade specific shows so he can take advantage of unknowing people. Next, all knives need different angles depending on the steel quality and the task that knife is made to preform. For example cleavers are typically sharpened at a 30 degree angle because they have to cut through cartilage and bones and need a sturdier edge to do so. Whereas your standard western style kitchen knives are usually at a 20 degree angle because they need a sharper edge to do more fine food cutting. Japanese knives depending on steel quality usually need anywhere from a 14 - 17 degree angle. Lastly your hunting/ pocket knives are usually from 22-25 degrees. The problem with pull through sharpeners like this is two things, one you can’t change the angle because every knife needs a different angle and two you can’t refine the edge any more using finer grits so you can’t actually get it past a certain level of sharpness which isn’t very much. They often even damage your knife’s edge. Next, knife honing rods don’t sharpen a knife. All they do is re-align the bur on an edge so it is straight as apposed to sharpening which is removing metal and putting on a new edge. That being said don’t over sharpen knives get good at maintaining them which you would do with a strop or a steel. For the everyday sharpener who needs to sharpen their kitchen knives and maybe a pocket knife here and there look into a guided knife sharpening system. Well priced ones to look into are Work Sharp precision adjust and a Lanskey guided sharpener. My qualifications for a sharpener are that it has to be angle adjustable and be able to refine the metal edge with multiple grits or stages so that you can actually get a really sharp knife. It’s hard to hold a consistent angle when sharpening, what The Work Sharp and the Lanskey do is clamp the knife in at a certain angle and allow you to bring sharpening stones down to the blade at the exact degree you want to set it at and refine the edge for a scary sharp knife if desired. All in all don’t buy this. Spend the same amount and get a sharpener which will work on all your knives and actually get a sharp knife. One thing I have to thank pull through sharpeners and people like Brad for is keeping professional sharpeners like me in business.

It's a shredder more than a sharpener. If you looked at the edge under magnification you could see the metal is just shredded to a jagged apex. Very hard on a knife edge to use this tool.

And that boys and girls is how you ruin the edge on a good knife. Anyone that uses these carbide sharpeners on their good knives either doesn't know any better or hates their knives. I'm cringing every time he hits that blade with that carbide.

There has never been a conversation between 2 people that know less about knifes in the history of conversation

There are youtubers and commenters that claim your sharpener doesn't work.... and that your absence at knive events is a hint to support their premise... WELL... i purchased a sharpensbest sharpener... in my first attempt, the knive got somewhat sharper and then very dull... But I am a logical person, I figured that if the sharpener was able to remove enough of the edge to dullen the edge then that means with the correct application of the sharpener, it could remove the metal in the correct way to provide a sharp edge... So I worked with that knife until I figured out how to do it... It became very sharp... I was to do the paper cut i see others do..... I have since sharpened most of my kitchen knives of different varieties and types of steel. I have sharpened three pairs of scissors, and one of them was a curved pet shear, which was not able to cut my pets hair, i also sharpened a small round can opener blade with amazing results...tbh i dont have to split a hair every single cut... i will sharpen the knives again when they fall off to a point that I am not satisfied with.... I'm not here to advertise any product. And I have comments all over the Web, praising and throwing water on products... But the sharpensbest works, and that's that

The water in your pipes isn't hot enough to damage the steel on your knife.

Those destroy knives! An heirloom knife had it's edge screwed up! Good work!

Washing in hot water will dull your knife through expansion and contraction. 🤣 Good one 👏👏👏

I totally understand the concept, and really appreciate the simplicity, but I just don't understand how you can get a clean bevel or maintain a sharp tip with these 90 degree carbide sharpeners. Clearly they work, but to me they seem more suited to emergergency sharpening, very rough tool sharpening, or even initial blade reprofiling perhaps.

The hot water thing has me laughing so hard! It's hot water not hot coals my friend

Those pull through sharpeners are a sure fire way to ruin an edge!

The old Gerber used M2 High speed steel (I'm guessing 60-62hrc) and were really good. I have a couple of small fixed blades from them. The new Gerber are mostly crap with a few rare exceptions here and there. There's plenty of harder knives out there than Gerber. Anything in rex 121 at 70-72hrc (though the Rockwell C scale stops at 70hrc) is almost as hard as the tungsten carbide which is about 75-80hrc. For those who are interested vanadium and niobium carbide are 82-87hrc with vanadium being a point or 2 harder.

We were up in the hills above Clinton, Mt. riding atv's in early Spring. Two of us stopped in a wide spot that still had patches of snow. Third one rode up, stopped, and said "What's that ?" picking up a folded Gerber knife. Tho stainless steel, it had rust on it from lying in the snow all Winter. I took it home, cleaned the rust off, oiled it. Didn't even need a touch up, still sharp. Gave it back to it's new owner and she still uses it as her EDC knife. ☆

You can hear him hitting it at the wrong angle when he's using the little finger sharpener shifting the blade from left to right really quickly as he sharpens it trying to make a little show for the people standing around but really he is making mistakes.

Old guys talking. Love it.

Fudd lore in action.

Gerbers are hard steel 😂

Love the guy who can't sharpen a knife giving advice on metallurgy. "don't clean a knife in hot water" You must have so much fun dealing with the general public at shows.

I was selling a guy a schrade knife . He did the thumbnail thing and took out a big chunk. Ive never seen anything bleed so much.

Great Video Brad love to see the knives get sharp again !

I found the best way to use the Sharpen-n-Spark, take the flint out and throw the rest of it away, that's what my trial-and-error led me to.

Never heard of the hot water effect this gentleman is talking about.

Love the guy who has a real dull knife and almost never sharpen his 40 yr tool is telling all you not to clean your knives in hot water

Oil stone, time and patience. Gives a very good edge.

Awesome stuff Brad!! Have an awesome Christmas!!

Maybe I’m being overconfident, but I feel like I could have done that with a Sharpal dual grit in less time…

Do you sell strops? once sharp with your device, that will maintain your edge longer.

I have a corona tungsten carbide blade sharpener I bought at Lowe’s and it works just as good if not better. Use a whet stone and your knives will last longer and be sharper. If those were that good why doesn’t knife makers use them

4:10 Guy in the flannel has no idea what he's talking about

lol hot water does not ruin an edge

Oh my word! Did y’all see the metal coils coming off the blade when using the V notch?

Now I know why my Gerber that is 20+ years old I can only get sharp with a diamond steel but I ordered the sharpener to see

Awesome

Why are people in this comment section so against these things. I'm a worker, I'm not gonna pull out sharpening stones while I'm on the job. Should you be sharpening like this all the time? No, but it's quick, it's easy, and when it's that sharp you won't have to re-sharpen it for a long time.

They worried that hot water will destroy their knives but they're ok with using that tool 💀

Brad I really would love for you to come to the Outdoor Expo in Rockland County NY if you are ever available when they have the show. Would be a thrill to meet you and I am sure you would do rather well in this area.

Would have loved to see the older gentleman's Chris Reeve...

It would be nice to sharpen such a knife with a good quality wet stone

Love to see him Sharpen my Benchmade Bugout with M390 steel with that, He'd be there for hours if not days.

The Chuck Norris of knife sharpening

Fantastic idea,wish I would’ve thought of it,wouldn’t use it to sharpen my knives,nevertheless he’ll probably be a millionaire with this marketing.Good on you,man.

Wenn ein Alkoholiker Messerschleifer verkauft

Awesome video! Love seeing the dull come to life again! Just received my made in the USA black long handle sharpener... cannot wait to put it to work! Keep up the great work, Brad! Seasons Greetings, Happy Holidays and Safe New Year to come!

Nice hat

Hear the man, extremely sharp knives dull faster 😂😂😂

The water coming out of the sink would have to be close the melting point of the metal of the blade to cause any changes. Some people just believe anything they hear and keep on repeating it over and over. And that "sharpening tool" is just a good edge assassin for any blade.

Thats nice knife

Imagine if that knife was actually sharp at the tip and only dull by the base. This guy could've cut himself badly

A classic older Gerber deserves better ...Just sad seeing being pulled through that thing.

Fiskars makes Gerber.

sandpapir 180/240 works every time

Oh god. That hurts to watch. How could somebody do that to a knife? Learn how to sharpen things for real.

Use that sharpener for 2 years and youll have a serrated knife.

I can't look at this. Who sharpens knives like that?!

One mo time⏲️

Don't wash knives in hot water ? Wth kinda old wives tale is that

Gerbers are really hard steel? They use 7cr. Wtf are you talking about?

Wouldn't sharpen my lawnmower blades with one of these sharpening systems

Having a hard time with these sharpener.

You can see on the paper that the cut is really rough

American sharpener vs Japanese. No contest needed.

i mean bro told him to get a lanksy not bad advice there

I’m just wondering what model Gerber knife that is?

Hello teacher, please explain what this is, is it a diamond? Thank you for your answer

This video is full of inaccuracies and absurdities. I tried listing what was wrong with timestamps but either YT or the person would hide it so I'll do it this way. First all, don't test how sharp a blade is by putting it to your skin. At the start of the video he only tested a small part of the blade before getting cute and running it length of it across the skin. That's dangerous Second. Don't use carbide "sharpeners." They mangle the blade. Use a stone or sharpening system. I've seen multiple blades wreck by them and even had to fix the edge on one myself. It took over an hour and was a pain in the a55! Third. Yes, if the edge is too thin, meaning the angle is lower than it should be, the more fragile the edge is. HOWEVER, you can get a "crazy sharp" edge at 16 degrees per side on a descent steel and it will not be fragile. The blanket statement of a "crazy sharp" blade getting dull quick is false. Last. Hot water coming out of your faucet WILL NOT hurt your blade. If your water heater is putting out water hot enough to make a knife blade expand, your metal pipes and faucet are not going to last long and PVC pipes will melt before the metal does.

I might as go from Toronto Ontario, Canada. Can I order wander as nice sharpenter from

WELL DONE !!!

What model of gerber is that cant quite hear it

The steel doesn't know it's 40 years old lol

Snake oil by the gallons.

Is Gerber steel hard?

Just like that

"It's that dull..." 🤣👍 (0:18) Definitely VERRY dull! lol

What happened to whet stones?? With my set of soft arkansaw stone and india stone that knife would have beheaded King Kong while he was still babbling about the carbide sharpener.. Nice fellow and good presentation of bad product.

I could have sharpened that knife faster on a stone than that. Geez

Do people still fall for this ? 😰🤦🏻

I've just ordered some stones, If they're good enough for Master Japanese Craftsmen, They should be good enough for me 😂

wher to bay ?

Do you ship to europe?

Two guys that don’t know nothing about knives unfortunately

How bad would the heat treating on your knife have to be for "hot" tap water to affect the blade in the way their talking about its laughable 😂😂

I have never been a fan of this style of sharpener. Not all knives should be sharpened at the same angle and this one removes significant amounts of metal to achieve said angle.

I spoke could you please tell me when you're a sharpener machines

Good for machetes only, Not knives.

Can’t wash it with hot water lmao

How can i purchase that in pakistan

Bet you coudlnt sharpen a rex 45 or m4 steel. M390 etc. That thing is made for kitchen knives with soft steel. Btw gerber isnt a steel. Its a knife company.

I can’t believe a guy like this is actually real…. He knows not a damn thing about knives, and he knows not a damn thing about sharpening. Yet here he is.

Are these guys serious???😅. What a joke

This guy is so hard to listen to just a know it all who treats everyone like they’re stupid

Stay away from this "sharpener"

Hi

Omg thats not sharpening, thats raping the knife 😢

What kind of old boomer crap is "dont wash it in hot water"????

Some guys just want to hear themselves. Have you heard of Chris reeves knives? Or if you wash your knife in hot water it will dull them. SMH

Great way to destroy a knife blade you would never touch my Victorinox

Now I'm satisfied I hope you are 😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂

All u have to do is look at his hat. It says I'm a tard and now it's time to move on.

Jesus CHRIST

😂
