Hi, Glad I've joined this community, This is the design I've made with Laser Cut machine. I need some tips on finishing it. It's length is 12.2 inch/310 millimeters and the blade's thickness is 0.275/7 millimeters. What's your suggestion on making its handle and the blade. By the way it's made from a leaf spring. I only heated it once, enough to flatten it. I also have designed a beveling machine for blade beveling which is shown in the second picture. It needs some corrections, The piston rods need to be attached to the bearings in their center. Any other thing to be corrected on it? Any suggestion will be appreciated so much!!
