Hi all. It's my understanding that springs can be used for knife making. But, it seems, when I look up what specific ones to look for, there's not a lot of reliable or consistent information. Has anybody here used leaf springs to make knives? What types of vehicles, models, year etc. should i be looking for? The guy who runs the local garage is a good guy and has agreed to keep his eyes peeled for me but he asked what specfic types to look for. I also understand that 5/16" is about the thinnest they were made, in general. Any tips on how to think this down or is it simply grinding it out (save on steel, spend on belts : ) Also, he's willing to give me all the old brake line i want to use as pins/tubes. Do these work well in knives? Anybody done this? I'm learning that the initial cost of the tools like the grinder and the bandsaw, while expensive, were not the costs I should've been concerned over. The cost of the consumables is brutal. The steel, pins/tubes, scale material, kydex, eyelets is crazy AND it's on going. Don't even get me going on shipping charges. Anyway, obviously i'm just looking for a way to save money by upcycling materials. Also, there's something cool about taking something going to the dump and making something usable and beatuful . As always, thanks for all the help guys. I really do appreciate having a forum where i can get help.
