I had a busy day yesterday completing more heat treating, grinding, acid etching and tons of hand sanding. I had two kiln running all day and went through a bunch of belts and paper! 
Here are some smaller ones I'm working on, they are made from 1/8" O1 tool steel and have a thin full flat grind. The grind is plungeless and on both sides.
I'm keeping the top one, it is a reject because of an errant drill hole.
This one is a slightly bigger Pocket Fighter in thick W2 tool steel. W2 is a higher carbon steel like 1095 but has vanadium added for fine grain and is made to high specs, it is a premium material that I hope to use more of in the future.
You can still see clay from the coating I put on the blade to go for hamon. I brine quenched this one!



Here it is after a full day of grinding, hand rubbing and acid etching. I machine ground the blade to 320 grit then hand sanded ("hand rubbed") up to 1000 grit, after that I etched multiple times in vinegar. (lol spelled wrong in the photo!) After each etch I would sand more or clean the knife to reveal the hamon, this has to be done repeatedly to bring out the features.
The softer steel above the hamon line etches more than the hard steel below the line, after many etch/sand cycles the knife will really look good! (I hope!)
