Starting with my first ever knife made from an old edger blade: It was more than likely mild steel, but I tried to HT with this crude setup before slapping some walnut on it with epoxy and brass machine screws for pins. I decided to get some O1 from Aldo. He's within driving distance and an awesome guy. I was roughing out the profile for a wharnecliffe when I thought it would be a good idea to practice on some scrap from cutting it out. Had just enough metal to make a small rat tail. I used this one as sort of a lab rat to practice some new stuff. Instead of a small belt sander this time, I made the filing jig Aaron Gough uses in his youtube vids. It was tedious, but I liked the control I had. I experimented with some filing on the spine, and etching the blade with salt water, nail polish and a 9 volt battery. Made a maple handle and rubbed on some linseed oil. I'm still learning and working out a lot of kinks, so feedback would be awesome. Here's some pics of the second knife with a bonus wharnecliffe-in-progress.
