What Did You Sharpen Today?

K390 Para 3 reprofiled and sharpened at 16 dps on the Kadet Pro this evening,
using 80, 150, and 240 grit Venev Centaur dual sided diamond stones.
Finished on a leather strop with 1 micron diamond emulsion spray.

This shot was taken just after setting the secondary bevel with the 80 grit stone.
 
fully rusted decades old boyscout knife. i think it was abused at some point no pun intended. with all the rust the edge bevel wasn't even visible. i didn't want to clean or treat the blade in anyway, i just wanted to sharpen the bevel right away.

i used 3 stages of RRS. knife slices now thru phone book paper silently.

AFTER:

The edge wasn't\isn't perfectly straight nor uniform, so a bench stone couldn't have done the job without taking off more material than necessary. RRS accepts any given and changing bevel angles (non-uniform bevel geometry) and manipulates just the apex. Took me 56min total. Also note that the job isn't messy at all with the RRS method: as one can see, 2 dry sheets of toilet paper (used one-sided) to the trash can, that's it. I really appreciate this.

I sharpened my two Victorinox paring knives. The cheap ones with the neon colored plastic handles. 1000 to 6000 grit stone then the leather strop. Sharp as a razor.
 
TwoSun 306 in M398. Not a typo! They claim it's actually M398, which is more wear resistant and less tough than M390. I've only ever seen it on knives costing upwards of $600, but here it is on this $150 TwoSun. No idea what the hrc or how good the heat treat is, but it should be interesting. It sharpened up quite easily using Tormek and CBN 180/400/1000 wheels. Took less than 15 minutes start to finish, reprofiling from 20/22 to 15 dps. Stropped on leather belts with 1 micron, chromox + .5 micron, and plain leather.

 
I found on side of the road about 3 weeks ago very bad shape iam thinking 3/16 to a 1/4 of the tip of blade was gone it took hours of hand filing I got the profile back and it's really sharp

I'm just curious how many people have ruined how many knives from obsessive over sharpening?

In my case it's probably 4-5, but I bought some very cheap knives just for that purpose. Probably sharpened each of them at least 20 times, until the bevels just became ridiculously large, and then thinned the blades and kept going.
 
Just received my first Kunwu knife -- the Zen model. Impressed! Fit and finish is top notch. Titanium, Elmax (61-62 hrc), milled Ti clip, and even a timascus collar on the show side for $210. Tall, flat grind with excellent uniformity. Measured 0.016" behind the edge from heel to tip. Sharpest factory edge I've ever received, averaging 120 BESS. It was sharpened at 19° on one side and 17° on the other. The only disappointment is that the jimping on the mohawk-style front flipper is too smooth. But the regular flipper and reverse flipping action are gold. Nice controlled drop shut.

I took it down to my preferred 15° dps using Tormek CBN wheels (160, 400, 1000 grits) and then stropped on Ken Onion with blade grinder attachment. Leather belts, starting at 2 micron and 15.5°, followed by 1 micron, chromium oxide + .5 micron, and plain leather at the sharpening angle. Finished with a few light passes on denim with Flitz.

Nice work. :thumbsup: :thumbsup: :thumbsup:
 
Finished up sharpening my Artisan Andromeda folder, using 220 and 500 grit shaptons and a light stropping on leather. I don't know that I will probably use my 4k shapton as I get hair popping toothy edge just from those two stones.

whittling a stray hair was pretty easy with that.

Great work, that is one great looking edge. Shows what can be achieved with only some minimal equipment, nice one. :thumbsup:
 
Thanks, that S35vn took a very nice edge and as you can see in the photos, I'm using cut off bits of bamboo skewers to set the initial height of the spine of the knife onto the stone, a reference point and then muscle memory to keep that same angle, right hand holding the knife handle while the left hand applies downward pressure and I can feel if the blade changes angles and correct that.

I have two other bench stones but haven't felt the need to continue upwards as the 500 grit seems to provide the type of edge I like for everyday kind of work.

500-600 grit is a great finishing grit for work knives. :thumbsup:
 
Sharpened my first ‘good’ knife, my Kershaw Blur S30V. It was supposed to be just a touch-up, cos the last time I used it on cardboard it was less than impressive. According to Kershaw, the edge angle is between 20-22 dps. Being that it was its first date with the Lansky, I did the Sharpie thing and started really light with the fine hone. What I found was one edge very slightly less than 20°, but the other side significantly more, like closer to 25°. What was supposed to be a quick touch up turned into an hour-long reprofiling session to get both sides closer to spec, most of which was with the course hone getting that bad side down to 20°. I was a bit surprised at how far off one side was from the other, but by the time I was done there was no more ink on either edge.

My only complaint with the Lansky is there’s no fine-tuning the angle between 17, 20, 25 and 30 degrees. Otherwise, after the first time taking the time to get the edge to one of those angles, it does a pretty nice job.
 
Got my hunter's license this year which takes a fair amount of money, time and studying here in Germany. So I thought I'd award myself with a proper hunting knife. I got a custom knife from Danijel Haramina. I already own one of his amazing Puukkos, so I went for one of his hunting knives this time.
It has a stabilized walnut handle and MagnaCut bladesteel.

I used vitrified diamond stones. 400 and 3000 grit and 1 micron diamond on leather and Bark River white compound on leather.
