I use this as part of my mobile sharpening business, and it's my workhorse. Awesome little system!

Thanks Steve for the confirmation of my planned approach. My Henkels paring knife's tip broke and I have the Ken Onion with the attachment and was pleased to see my thought process followed your demonstration. Especially appreciated the temperature by touch means you spoke of. And for future videos, more showing the tool's use and less blathering away by the other guy.

I sharpen kitchen knives for my neighbors.. lots of seriously damaged knives. The blade grinding attachment is terrific. I could never make the time to do 4-6 knives at a time. The WS is very fast compared to the bench stones. Thanks for the video 😎👍

Awsome job. I used the original work sharp to put tips back on 3 different knives, 2 daggers and a folding knife. I do really want that blade grinder though.

Works great on those kitchen knives with a VG10 core, the brittle tip is so easy to break off, have repaired at least 2 of mine using this same method. Cant even tell they were broken.

I've got a colibri pen knife with a pretty gnarly tip (Somebody tried to pry with it is my guess). But I love the brass engraved hunting scene on the scales so I want to salvage it. This vid is great. Thanks men!!

Very cool just be careful when putting the tip on for too long you can affect the temper of the steel as long as it doesn’t change colour the steel won’t be affected

My blade grinding attachment is on the way and have the benchstone on backorder. I wish worksharp would sell the accessories on there website on Amazon. I want to order the 15°/17° angle guides but with shipping its cheaper to buy the whetstone unit the come with.

I've got the Ken onion model electric sharpener. But want to get the X45 Belts for it would those be a good choice . I'm just curious because your web site says those are used for the initial shaping of the convex grind. And the X22 is for the final shaping or is the X22 belt good enough..

Why don’t you put a level platform up there where you are grinding instead of relying on not changing the angle of your hands? Why do you sometimes use the upper part and other times the lower part of the belt ? I can’t get the hang of sharpening. Where can I purchase this tool? Thanks, Paul

Go for the work sharp precision adjust knife sharpener it's relatively cheap and it's upgradable I had no fucking idea what I was doing for the longest time and I bought that like 4 weeks ago and I have done 3 knives so far working on another right now hence why I'm here now 😂 but yeah the precision adjust is great to learn on and you can usually find decent information about your blade angles online if you wanna try to stay close to the manufacturers edge geometry mind you I'm like a overly educated gorilla not a college kid

Now I know how to properly repair a broken tip on my "Western" hunting knife that I abused as a youth 52 years ago.

@podboq2 2 жыл бұрын

Exactly the method I was looking for - only problem is, the tip that I need to repair is on a Burnley Kwaiken - with a flat spine…. Due to the flat spine, do I want to grind up towards the spine from the edge? If not, I’m not sure how to proceed…. I’m using a Ken Onion Work Sharp, but don’t have the blade-grinding attachment - I’ve only got the 15°-30° guide. Tell me what to do, fellas…. and thanks for any replies from the Work Sharp crew!

@WorkSharpOutdoor 2 жыл бұрын

This one depends on how much of the tip is missing. If it is a very small amount, you could grind off the material with your current setup. Just keep making passes, stopping with the "tip" of the knife in contact with the belt until the tip is restored. If there is a significant amount of the tip missing (the more likely scenario) you will likely need to grind down the spine of the knife a bit making it into more of a drop point. That would be a challenge without the Blade Grinding Attachment used in this video. The drop point approach would be to follow the instructions outlined in this video. You can always reach out to our awesome customer service team for additional support. info@worksharptools.com They are great at tackling stuff like this!

@@WorkSharpOutdoor I lost the tiniest amount of tip on opening the knife once, I flipped it and the tip hit a piece of metal and snapped off - about a half millimeter was missing, just enough to tell that it was now square instead of pointy…. So I worked on it last nite and now my tip is rounded - I think it may be better off (i.e., stronger) round rather than pointy. The curve is sharp and being sharp it still can be used to pierce, but it’s not so fragile now, I think, as it would be if it were pointy. I may try to teach myself how to shape a blade using some junk steel, until I figure it out, before I work more on this kwaiken. Thanks for responding and interacting with me!

@mrdjtoday 3 жыл бұрын

The method of grinding down the spine is a great idea, but I have to ask. If the break of the tip was bigger could you still just grind down the spine or would you have to also grind down the cutting edge also to re-establish the tip? Or, would you just grind down more of the spine and leave the cutting edge alone? Please let know because I really like the idea of just grinding down the spine, it makes a lot of sense.

@jukio02 11 ай бұрын

Don't you think it would be easier to use the vertical grinding area? You will be able to find the angle much easier. That's what professionals use, a vertical grinding belt.

A power grinder can reshape and cut a tip back to shape fast if using the knife is more important than 'geometry' and tool use by an expert.

I mean lets be honest the worksharp is brutal on knife points! its a great sharpener, i love it, but boy ya gotta be careful with your tips.

@WorkSharpOutdoor 4 жыл бұрын

Brutal only in the hands of the hasty. make sure to stop sharpening before the tip crosses the halfway point on the belt. Either lift the knife off or stop power on the Ken Onion or Original sharpener. Steve shows great technique here.

@rifleshooterchannel208 4 жыл бұрын

Yep. The only reason I see knives needing new points is *because* they were mutilated by Worksharps. Thankfully Lansky sharpeners exist and can quickly correct the issues.

Rifle Shooter Channel I’ve used a worksharp for many years and never messed up a tip. Would be a good idea to maybe use the product as detailed by the manufacturer. Sometimes reading instructions is beneficial.

@jkilla9934 3 жыл бұрын

This method of feeling the blade gives no indication about the real temperature at the sharpened part at all. First of all he feels the sides of the blade and not the place where he sharpened. Second he cannot feel it WHILE he sharpens and he mentions himself that it cools down very quickly. The hints in the product documentation and also on the box for the replacement belts are very misleading. It is super easy to overheat the edge when sharpening with power tools without constant cooling.

@KickMe1177 3 жыл бұрын

Yeah if you are using a super coarse belt for long periods of time. If you are just sharpening a blade, losing the temper on the blade is very unlikely.
