Craig,
I use "electrical friction tape" on all my knives, it really locks and holds the knife in the vice with no residue and no over tightening. Another thing and I know it won't help with the SOG but with folders, especially those with heavy handles is I fold the handle up 90 degrees so I don't have all that weight of the handle hanging out there.

Wow, that's pretty impressive. One of the reasons I purchased the PPII is because I have a pretty extensive collection (about 28-29) Lie-Nielson hand planes, most are bronze and I thought I could figure out a way to sharpen the plane irons on the weps. For the irons that have a slot in the blade it was pretty easy. Just stand the blade on end (vertical)and centered in the vice. The top screw of the vice goes thru the slot of the blade to clamp and the bottom screw of the vice can either push against the plane blade or go thru the slot to push against the movable part of the vice. I've done several blades now and they turned out great. I had to play with the angle of the rods a little to get the right angle but with the angle cube it was easy. I'm now working on how to do blades without slots and then on to chisels. Just a FYI for any woodworkers out there.

My "go to" hunting/kitchen knives are KOA Jaeger boneing and Cub Bear. Both D2, both sharpened to 17 degrees. They get a lot of use piercing food packaging, working around bones etc. They take a great edge and polish nicely. Vary satisfied

Not only for the example you gave but for getting the same angle per side, because the knife is off center, the angle cube is a MUST HAVE.

Hello Sauce
In addition to all the other good advice I suggest using electrical "friction tape" (can be found in the electrical department of any hardware store) You will be suprised as to how solid it locks the knife in position with vary little pressure on the vice especially when above the top gage holes where the vice has the possibility of bending. I use it all the time on every knife.

The second photo was vary impressive. I think I'm about 6.7M strokes behind you

I'm not an electrician but it's labeled "friction tape" and have seen it used to wrap electric wires. It's also use to wrap something you want to get a good grip on without being too sticky kind of like "sticky note paper" would be. I use it on the grip of my hunting bow. It can be found in the electrical department of any hardware store. The 2 key things about it is that, it's made of cloth not plastic film so it has some cushining to it and it's sticky on both sides. Glad I could help with the toothpicks Damn, I wish they had spell check on this thing, hint hint.

I use a flat toothpick as a gage on top of the two pin depth gage for those in between situations like narrow blades, instead of just eyeballing it. I also found that electrical "friction tape" works a lot better than painters tape,foam tape or moleskin. It's only a little tacky on both sides with just enough cushion to compensate for the irregularity of the metal to metal contact and the "tackiness" (a new word of the tape sticks to both the blade and the vice when clamped with vary vary little,if any, residue afterwards. For FFG blades I'll double up the tape with a small (1/4 x 1/4 inch) piece to compensate for the taper just as the blade leaves the vice. I found this tape really locks and holds the blade in place without over tightening and bending the tips of the vice.
As long as you only sharpen at home, a small dedicated car vacuum with a hose and a brush nozzle is a fast and effective clean-up when changing to the next progressive stone. They are not vary expensive. Just be carefull of your hand and arm movement around that exposed blade.

Kevin, Semper Fi back at you
