Title says it all. I want to see those blades. We all seems to be decent if not freakin awesome at sharpening our blades. And since I have never seen a scary sharp knife I'd love to see some great pics of the edges on the EDCs of some of the stone masters. Do you prefer polished, toothy, razor honed. The sharpest of the sharp on display.

Please? :D
 
Guess I'll get this started. The edge didn't show up too well, but you get the idea from the pic. I go for polished, this one could actually use some touching up as its been my EDC all week, but it was good enough for the pic. Thats a peice of standard printer paper.

Its a little O1 folder I made. Its the 4th or 5th knife I ever made so its got some fit and finish issues, but its a pretty good cutter. I ground it really thin, and there just isn't much out there that cuts like O1 :D

Nice folder. I have no experiance with O1 steel unfortunatly but the consenses seems to be that it takes an awesome edge. If that has been a working EDC for a week and still fillets paper I'd say it's a nice chunk of proof.

I have no digi cam at the moment but I'll take a few snaps and either scan them in or something. I'm experimenting with sandpaper on a block of polished marble. Sharpening my CS Recon 1 Tanto PE with it. The secondary edge was easy, just pretend it's a chisel. The primary is going to be a pain. Mainly cause I am just starting out with freehand. But if i want a shaving sharp edge on it I'll have to learn becuase for some reason my Sharpmaker just won't sharpen it right.

Always leaves a bur. But I think the stand may be deformed a bit. The stones are really loose in the holes and when pressure is applied the almost bend back a bit. A good 3-4 degrees I'd say. I'll just send it to Sal and see what he and his kin think. If I suck, well crap. If not I'll order another stand.

Thanks for posting your pic. I was surprised this thread hadn't gotten any hits after the 1st few days.
 
Guess I should have added that I sharpen free hand using benchstones, then strop. The O1 I've been using will take an edge so smooth it slides off of things like nylon rope. For a user edge I generally take it up to a hard arkansas and strop to take the burr off, then go back and make a couple passes on each side with a soft arkansas stone. Then hit the strop a few more times. This gives it a WICKED edge :D


Having the rods flex on your sharpmaker probably is making a difference. Your not going to get a consistant angle because you will use slightly different pressure each pass and get a varying angle. I really think everyone is capable of doing a passable job at freehand sharpening. You should do just fine with your sandpaper set up after a little bit of practice.
 
Well first I use 1,000 grit, then 1,500, then 2,000. After that I just flip the 2,000 over and use the paper side. Gives a great looking edge but the thing still won't shave much less pop hair off my arm. I have tried stropping on both blue jeans and mousepad. I must really need practice at the because I think my lift off is bad and I keep rolling the edge over upon picking it up. :grumpy:

Ritter RSK Mk.1

Sharpened at 21° with my Edge Pro Apex, stropped at 24° with Flitz on a leather "stone" I made to fit the Apex.

Here's my Doug Mondt GMC in CPM-10V. It's a bit of a "perspective pic", the blade is only 2 5/16" from the start of the grind to the tip.
EdgePro 3000 grit mirror polished back bevel at ~20 degrees included, with a 40 degree final edge for easy touchups on the Sharpmaker. I use the corners of the white stones, followed by a linen strop, and "unloaded" leather strop. I call it my "cardboard knife". Puts a zipper in cardboard, and holds an edge like nothing I've ever seen. It's my only 10V knife, and along with INFI, it's the easiest steel I've used to restore a hair popping edge on. Usually just takes a couple of strops per side on the leather strop, even after cutting that would have left most knives feeling like a butter knife. Takes a very aggressive feeling edge that grabs and pops individual hairs even at a relatively high polish, and after extensive use. Like now. It sees regular use, reducing cardboard boxes into bite size portions(guess it's a knife nut thing) and I don't even remember the last time I touched it up, but it still shaves like a Mach III.
 
It's 4 in the morning, and y'all have me taking pictures of knives:rolleyes::p
My favorite cutter, though I tend to baby it most of the time since I want it to last forever (forget that I chopped it into a coat hanger right after I got it to see if it would chip).
Rinaldi TUK in CPM-S30V. Same technique as with the Mondt, though the back bevel isn't at as low an angle. .015" at the start of the back bevel, .005" at the secondary, or final edge bevel. Goes through stuff like a laser beam. For kicks, I balance it on my hand, and cut 8x11" printer and notebook paper by pulling it straight up into the edge. The knife doesn't move.
 
This is my sharpest knife - An SE CF Delica
(oh, this is just the <razor-sharp> factory edge, I'm not a stone master but just thought I could share the pic :) )

Awesome pics guys. Seeing edges like these really show what time and skill can do. Truely very cool.



I have to ask Ted, what camera did you use to get that shot of the serrated edge?
 
I think I could have done even better with the tomato - but I grabbed it from my wife while she was making a sandwich so I rushed the cut. This is the BM Skirmish, and the corners of the paper were sliced off with it too...

Thanks Erint, it's an Olympus C8080WZ. 8 mega pixel with a real good macro. This shot is a crop of a larger pic, reduced to 50%. I'm just going outside to shoot some pics of the Spyderco UK Penknife. I'll try some more close-ups.

I like a very thin polished edge. Sorry my photography skills aren't up to par.

Does anyone have experience with O-2?
 
18" HI Sirupati style khukuri.
Blade steel: Mercedes leaf spring and convex edge.
No really scary sharp, but if I had to check on things that go bump in the night with just a knife it would probably be this one:

That's sharp!!!
 
Guys, try the toilet paper test. If you have some of that thin cheap TP, like Scotts, just pull down a foot or more and see how many sheets you can slice through without tearing. You should have a clean slice.
 
I sliced through 3-4 sheets of Scotts one-ply toilet paper with the Spyderco Calypso Jr. It has a 20 degree per side edge on it. I reprofiled it to 15 degrees per side, if not thinner, and then put the 20 degree edge on with the Sharpmaker, finishing on the ultra fine rods. I then stropped it a little. Eventually most knives will catch and tear the TP. See how many free hanging sheets you can get through. I keep a roll of TP on a metal bar suspended from my basement cieling for testing purposes. :)

For the heck of it I took a swipe with one of my junky straight razors that has a less than perfect edge and it sliced even better. The picture came out blurry so I'll have to try it again. I got through more sheets and it never caught and tore the paper. If you want to see sharp, check out a straight razor, and this one wasn't even as sharp as the ones I shave with, but I didn't want to abuse my $150 straight razor by running it through TP. :)

I darkened the image in photoshop to better show the toilet paper (it was a bit blow out from the Flash), but I isolated the knife and didn't darken it so you could see it, so that's why the picture looks a bit funny.
 
Here's a close up picture of the Calypso Jr.'s edge. Not a pretty side. There are a lot of scratches as you can see. Under an electron microscope it would look even worse. :) When I sharpen my straight razors I use a 100x microscope to inspect the edge. I can see scratches after finishing on a 4000 grit water stone. Then I go to 8000 grit and the scratches become harder to see. After some stropping thery are almost gone completely at that level of magnification, but I'm sure if you had a more powerful magnifier you'd pick up the finer scratches.

This image was captured with my webcam which has a wide focus range. You can actually unscrew the lens from the camera, so if you unscrew it almost all the way off you have moved the front element far away from the CCD chip allowing for very close focusing, but the depth of field becomes very limited. I had a bright light inches away from the blade to improve the clarity.
