The knife with the deer antler is actually my first knife i ever made. This was made in my garage. I hate to say it, but this knife holds a terrible edge, but it looks good.
The third knife is one of my best, you can shave your arm with it! The jaw bone has a crack in it, so its not very strong and just for show. The blade is also made from an old Nicholson circular saw blade.
The sharpie balisong was made from a saw blade, and well, sharpies. All credits go to the actual person who designed it on Youtube.
The mini butterfly knife is made from a hacksaw blade, 8 popsicle sticks, paperclips, hot glue, and 2 clothespins.
The next knife is actually pretty sharp, made from sheet metal and an oak log, it's actually pretty good for my 2nd knife.
The next one is my switchcomb converted to a switchblade. I took a switchcomb, took out the comb, and put a sharpened hacksaw blade in there and hammered down the surrounding metal.
My most recent knife is a full scale rambo survival knife. Its made from a file, so it has good quality steel and will hold an edge for a long time. It actually can fit a mini survival kit inside the handle.
Final Picture: all my homemade knives together
