I was checking some of my projects (water collection system from the AC unit drains) and noticed two cheap rusted knives that my wife was going to throw in the garbage . Blades were bout 7 inches each and they were not full tang.

I am not fan of throwing anything, no matter how useless it is. So, I used the Dremel to cut their blades to 2.5 inches. They are not less cheap now, but since the blades are much shorter now, they are more controllable and useable. They sit on the workbench and already started using them. They save better knives for more important jobs
