I have been making leather dog collars for a while now. I am small and have fairly weak hands. I started out with a basic rotary hole punch that I got at a local craft store, but I had trouble getting it to punch through the leather straps. I bought a Herm Sprenger leather punch and for about three weeks it worked great, but when I went to use it last I noticed that the punches don't line up anymore and the alignment has gotten so bad by the end of working on my collars it would no longer punch because the alignment is so far off. I am a college student, so my budget is fairly limited. I am looking for something $100 or less that will cut clean holes in leather and that my hands will be able to manage. I was considering something like this:

But I didn't know how it would do punching through leather. Any advice? Help!
