Only Sharp Knives Are Interesting- the Sharpening Thread

Anyone tried to hand grind the primaries grinds?

Apart from DEK3, I think other CPK knives I have (apart from Behemother) would benefit from thinning the primary grinds. I prefer good slicer rather than though use knives. However, I am not willing to try as it will change the finish which is not a huge problem because I may and up with hand rubbed finish if I do it correctly. But my concern is I will not able to maintain the "S" shape on the primary grind. I might try on UF2 and Kephart since (as far as I know) they do not have "S" grind.

Before trying that I will try to sharpen the secondary grind (i.e. the edge) to more acute angles. But I doubt it will help greatly in increasing the slicing performance.

Hey bud I’m likely not the best person to take advice from here but thought I’d give you some kind of answer… my honest thoughts on this get a knife made thinner and designed to be more of a slicer from the get go. For what we pay for these cpks and what most of em are made for (hard use) I wouldn’t get too far into changing geometry that much and like you said be careful with what grind it’s starting with. My 2 cents anyway!

Thanks yoko! For my first run I’m super happy! Shit pic but… This thing was a hot mess… had to straighten the tip etc etc etc. took from 150 - 1k grit with the included diamond stones. Didn’t bother balsa strop and gunny juice for this one. Def issues on both ends tip especially.. I let the stone roll slightly when profiling initially apparently but hot damn!! This thing is sharp!! Lol kinda idiot proof but I tested that 😂

Thanks for humoring my questions yall! I’m a fan of asking the dumb ones when there’s a good group that has come before me rather than make all the lil mistakes that I’ll likely still end up making haha.

A lil squirt of white lithium grease I had around did the trick btw… feel like it’s a good idea on this setup…

More will be revealed…. Have a good night gents.

Yeah I agree with that. On the other hand, I like the quality and working principles of CPK. So I do not mind putting some work into those knives to make them a bit more oriented for my use as long as I do not mess them up :) But as you said ad long as the spine is thick there is so much I can with hand grinding.
 
Getting the hang of the tsprof for sure. Finished with 6micron strop. Going to take it out this weekend in the woods. Impressed but part of me feels I don’t need such a smooth edge… it’s pretty awesome but I kinda like more bite! Idk maybe I’m just used to rougher edges… time will tell!!

Slices paper towel pretty good… not bad for BFK… #notslicey

If you want a toothier edge, just sharpen up to a lower grit. Instead of sharpening with 1500-2000 grit, maybe try stopping at 600-800 grit. It just depends on the edge you want.

You could also try a dual grit edge. Youtube has a few videos on it. It seems to make the edge last longer, but I prefer the way a single grit edge feels more. YMMV

Good to know! I was thinking of more in terms of polish and going in line of grit where it’s just more work typically to skip up like that… that makes sense in terms of simply refining the burr and leaving it rough. Took that to 1000 grit before strop. Thanks man I’ll try that on the next run.
 
Anyone want to share how they clean their strops loaded with diamond spray? I’ve been using one for a bit now and the surface has turned a decent shade of dark grey and it doesn’t feel like it’s working as great as it did a month ago or so, I figure it’s best not to just spray more emulsion on it?

According to Don, who was the source of the diamond spray I sent you, and, I think, your strop as well...

To clean either as they load with metal I simply wipe with paper towel or use a large pink eraser and only re-apply spray as needed

By either he is referring to basswood or leather.
