Here's a bit of a funny story, skip below for the actual question.
I've been getting more and more into razor restorations lately and have been enjoying it a lot. Recently I took on the lofty goal of creating buffalo horn scales from full buffalo horns.

Without a saw.

I bought a coping saw. You can guess how that went, an hour or two of a sore arm and ugly misshapen scale blanks that didn't turn out. So I set up my dad's spare tile saw and bought a belt sander. Trying to figure out how to cut nice square scale blanks out of lumpy buffalo horn was interesting, but somehow I pulled it off, albeit with wasting a ton of horn. The scale blanks were thick, almost half an inch, and pretty uneven though I was using a guide.
I was able to sand them down and make some pretty decent scales, but this adventure has made me want to purchase a small saw.

So which is better for working on scales, a band saw or a scroll saw? What would you buy if you were starting all over? Also, where do you purchase your horn for scales? Anyone else ever started with the whole horn?
