I had made a few knives in my day, and one sword (long long ago, and no, I don't still have it).

One of the places that has been around for awhile that has a good selection of supplies AND kits (for the beginner up to the master smith) is the Texas Knife Maker's Supply store

Another place that looks good, although I have never dealt with them is the MidWest Knife Makers supply

I also came across a place to get a Sheffield's Supply Catalog on line.

And then there is always the Jantz Supply site.

I hope these prove to be useful to you.
