Hey guy I'm cutting holes in webbing with a punch but wood end grain is to soft as the webbing sort of pushes into the wood and doesn't cut fully. I tried a plastic cutting board and that does better but still not a clean hole, I usually have to burn the rest out. Is there a hard surface I could use without damaging my edge? I'm using WUTA punches

How big of holes, alot of the time holes in webbing are melted rather than punched,

I used to make a spacing strap our of nylon webbing and brass grommets. I would chuck a standard punch into my drill press. Set to a medium speed and use it to bore through the webbing.  The punch generated enough heat to melt as it cut and I had perfectly cut holes.
I used both wood and plastic cutting boards as backers.

Try delrin or acetal as a block. I use both these as pressure bearers when stamping using my bench press. They are harder than HDPE or nylon plastics, but soft enough not to damage a hole punch edge

Toms right. I just use a battery hand drill with a hole punch down on to a plastic kitchen cutting board. Same thing works well for sharpening the punch onto a fine sanding belt as well. Try going through something like this without a drill and punch.

The traditional base for hole punching into is a very thick sheet of lead or a lead block. When it's worn, you melt it again

I had one, but it was stolen. Now I use a thick magazine as a base for punches and stitching chisels and replace it when it gets worn

Of course, the punches should be very sharp

tbh, no matter how sharp the punch or hard the surface I never get a fully clean cut hole. There are always fuzzy hairs which need burnt away

Try the drill press or hand  drill route
