| How I build a custom knife |

| Blade:
Hello, I will cover the steps that I go through to build a custom knife in the following pics. The first few pics show how I lay out my parts, If I don't have a steel pattern I will use a printout or copy of a cad drawing or a hand drawn picture. I cut and spray glue the drawing to the material, in this case .125 titanium. The process to make the blade is the same as the handles or scales, I already had this blade made and heat treated, so that process will have to be shown in a future post. |
| Blade:
The next pics show how I clean up the blade on the disc sander to remove the burs left by the saw. Then I mark the holes with a punch and drill with a 1-72 tap drill. |
| Blade:
I drill the front side first or in this case the back because this will be a left handed knife :wave: which means that it is set up with the lock to be pushed by the left hand thumb so it is on the right hand scale. Then using small vice grips I clamp the two scales together and drill the second one using the first as a pattern. While I was drilling the second scale I broke the drill, the second pic shows the tool that I used to remove the broken piece which you can see in the third pic :doh:. |
| Blade:
The next step is to tap the holes on the lock side scale, I use a tapmatic for this step but hand tapping works just as well just use a guide and you wont have any problems. Then I clearance drill and countersink the holes in the front for flathead screws. |
| Blade:
Alright, it's getting late so I will show the next few steps and then cal it quits for now. After the countersinks are done I screw the two scales together, then I drill and ream the for a 7/32 pivot pin which is the pin that the blade swings on. After that hole is done I place a try pin in it to hold the two halves steady and drill and ream the stop pin hole for either a 9/64 or 5/32 pin. The stop pin is what the blade opens and closes against. |
