Hello ftom the deep north of Canada and thx for your video! I foumd out rhat with the grinder if you want to get rid of the burh comlelty i keep going finer belt grid til the strop belt 5 passes each sides and always finish with no burh at all left and not only great quality of the blade but keeps his sharpeness extremely sharp a long time before sharpening again! After each sharp i also do 3 4 strop passes on the block!!! For the rest for a while before sharpening again i use a ceramic rod to keep it sharp and edgy! U are the pro here but i have been using worksharp grinder for 2 years now and this is my way of working with this great machine! Thx again God Bless Frank from thr north!

Thanks for a great video. To get a more accurate angle I attach a round spirit level that is sold on Amazon to the knife and while the bubble on the target at the center the knife will stay level with the platform. This reduces the number of times that i have to put the knife on the platform each time.

I use the Ken Onion with great results. I don't use the attachment. As needed, I progress through the belts from 220, 800, 1000, 1200, and 5000 for stopping. I get a very usable edge. I'm not after the same edge as you do. My knives are used hard each day. Using the 800, 1200, 5000 to renew the edge!!

If the edge isnt hot, indont see how the steel could soften
@EngineersPerspective7012 ай бұрын
The trouble is the edge apex has an extremely small cross section. Does not take much to heat up less than a hairs width of steel and you can’t tell by touch because there isn’t enough thermal energy store to be felt by your fingers. If you can tell by touch, that edge is for sure toast. Not the whole blade though.

Couldn’t you use a ceramic honing rod to get rid of the burr. Then Strope.
@EngineersPerspective701 Жыл бұрын
That’s exactly how I maintain my German knives. The ceramic would still leave burr that is generally smaller and less fragile than what the belts give. That said, when I follow up with the strop it definitely cleans up the edge but does seem to leave a tiny foil burr once again. Long story short. It’s a totally acceptable edge but still not perfect due to residual foil burr.

So, I've been trying for over a year to find a way to sharpen my knives. I've tried by hand, ruined my knife, gave that up. Lansky 2 rod box with ok results. Landsky angle rod and stone kit, got no results. I just purchased ken onion sharpmaker and got cutting paper results, but i have already scratched one of my knives scales trying to get the entire blade. Now I'm debating to buy this attachment? I'm wondering if there is something I'm missing? I seem to never be able to get that burr that i can feel... Is this why I can't get razor edges? Or is it the angles? Btw my knives are s30v cpm3v,D2,Aus10.. I did get a burr on my cheap kitchen victorinox paring knife. At this rate it would be cheaper to just buy new knives when they dull. 😆🤯
@EngineersPerspective701 Жыл бұрын
Sorry you’re struggling. I hate to say it but yes you’re missing something. If you do not form a burr, the knife will not get sharp especially for a beginner. Find your angle and keep sharpening away until you form a burr. With the ken onion you have go: 1) 10 strokes on 1 side with coarse belt then feel for a burr, not there. 2) 10 strokes on other side with coarse belt then feel for a burr, not there. 3) 10 strokes on first side with coarse belt then feel for a burr, it’s there. 4) 10 strokes on second side with coarse belt then feel for a burr, it’s there. 5) move onto finer belts progressively while alternating sides as appropriate to finish.

Thanks for the video! If I sharpen a knife on the slowest speed and use very light passes do you think it will still ruin the heat treat along the edge? I use this system but now I’m afraid to because you said it can weaken edge retention. Maybe I’ll just use it to put a 20 degree bevel on my knives so I can sharpen them with my spyderco sharpmaker for all future sharpenings. I recently used the worksharp to put a nice edge on a fairbairn Sykes commando knife and it worked out very well. I used the slowest speed and did many extremely light passes barely touching the belt. It too a long time but I managed to get a hair popping 50 degree inclusive edge which impressed me.
@EngineersPerspective7013 жыл бұрын
At the end of the day if you’re getting satisfactory results then don’t sweat it! I’d recommend putting a 17-18dps edge and doing a 20dps micro bevel with the sharpmaker. Works much better! It’s hard to say to the extent it’ll affect the edge retention because it depends on steel and what you’re doing but unfortunately I can almost guarantee it will not be as good as a nice hand or system edge. Other than potentially burning the edge slightly you can drastically affect edge retention by the type of sharpening. What abrasives, grits, etc. For example I get 60’ of fine edge retention on S30V with a DMT fine followed by 1um strop. If I finish on a 1200 grit ceramic then it drops to 40’. All cutting cardboard on a 1” section until no longer shaving.

I love my sharpmaker kit and I also have the diamond rods and ultra fine rods. I also have a lansky turn box that can do up to 50 degree inclusive. I have a few different clamp systems but I swear I always end up with super wide bevels towards the tip of my knives.

Obviously the limit depends on the particular steel, but I don't believe you are doing any harm to any steel's heat treat when it's only warm to the touch. Most manufacturers (even custom blade smiths) produce their factory grinds on a belt or grinding stone.

So I actually did a full blown edge retention test on s30v comparing stones to this system. First video of that series came out yesterday. Won’t giveaway the results here but I agree that for the Worksharp it’s more complicated than it will/won’t! In terms of factory grinds, it’s an undisputed fact that the heat from the non-water cooled belts/grinders sharpening substantially effects edge retention. It is not uncommon to double edge retention by hand sharpening away the “burnt” steel. Kknivesswitzerland did a test where his friend ground a blade with no sparks and kept it “cool to the touch” and then hardness tested it. It had lost up to 10HRc in some places despite them being very careful. Just because people do something, doesn’t make it a good idea. I have the Instagram post screenshots of you’d ever like the see them just let me know!

@@EngineersPerspective701 Oh interesting! I wonder if he performed the same testing on the hand-sharpened blades to make sure the variability wasn't simply endemic to the knives he was testing? In any case, I'll be very interested to see the results of your test. Personally I love the Work Sharp Grinder for its versatility and speed. I've sharpened lawn mower blades and machetes on it, as well as EDC and kitchen knives. That said, the best I can do with on the BESS tester is around 160g, whereas I can reliably get below 100g with the KME. But the KME can be slooow. Waiting on the arrival of my "Beast" plate, so hopefully that will speed things up. Thanks for the interesting content!

@@BladeLabMiami His test was actually on the main grind of the knife and it saw that much softening! So a little concerning but the size of belt grinder and the belts used make a big difference too. Steel was 12C27 I believe without going back to look. I actually learned how to freehand just because the KME was so slow! I also struggle to get the results I want on the Worksharp but that's driven me to do A LOT of experimentation! I've developed a method and skill to get X50CrMoV15 of varying hardness to at max 120g BESS and did get S30V to the same sharpness for the upcoming tests. I also have a video coming out on Nov 1 getting CTS-BD1N at 63HRc to score 83g average. Can get LC200N about the same as well. Not as good bite as a hand edge but still very nice!

@@BladeLabMiami I was also super blown away by the sub 100g score! I use the stiff belts but I can't say if they are the difference makers or not. Settings: 1) Closest wheel position like you do. 2) Increase belt tension on the tracking wheel 3) Lowest speed 4) Light pressure but enough where you're consistent. Technique (This is a lot!): 5) Apex the edge completely on X65 or coarser belt. 6) Minimize number of total passes on belts above X65 (3-5 passes per side) 7) Alternate sides on each pass starting on the belt prior to your X4/X5. 8) Do 5 passes per side alternating on X4/X5 to REALLY weaken burr into thin foil. 9) Pull edge trough soft wood, hard felt 2-3 times. 10) X4/X5 alternating passes checking edge with 3-finger test to feel when it just starts biting again. About 2-3 per side. 11) 12,000 micromesh belt at ~1 degree less angle checking on BESS tester after each pass. If no improvement after 2-3 passes per side then increase angle by 0.5 degrees and try again.

Thanks for the vid. I don't have the stiff belts, so I try to sharpen as close to the top roller as possible to get a more flat bevel. I also do my best to go from a burr to knocking it off with as few strokes as possible. Lately I've been jumping from the x22 straight to fabric honing. You're right it's easy to overpolish. And I never run it above half speed.

Sorry for coming on strong, but I still maintain that there is zero difference between this and a cutting board. If you go straight to the strop the burr will continue to be drawn out and the edge will prematurely fail after sharpening. If pulling a fresh edge through wood reduces sharpness of then it is not sharpened correctly. I've proven in my own sharpening that it is extremely difficult to remove a burr on these soft steels with stropping strokes only on any substraight or system. Lookup the "Knife Deburring" Book, he displays the most effective method I've seen but it takes a lot of equipment and accuracy that most don't have. The point of drawing through the wood is to mechanically remove/reduce the burr which is successfully done in the video eventually but I feel that pine is NOT super effective but is easily on hand. After the burr is removed/reduced to the best of your abilities then feather in the final edge without drawing out a new burr using minimal strokes (did too many on the paint stirrer in this video IMO). I have other videos that show this same process with BESS testing. A towel of the proper fabric can be pretty effective as well but a lot of leather products/setups don't really have the right properties I find to remove the burr.
