has anyone gotten one of these?

I've owned both the Colt Steel and Windlass versions.

The Cold Steel one is, as Hotspur said, sharp. I had huge issues with the grip size, though--it is ridiculously large, and horrendously tacky.

The Windlass has the same blade and a much more tasteful grip. The Grip on mine had a loose crossguard, however, and eventually the pommel cracked.

Neither are copies of Persian pieces, as has been falsely advertised. They are semi-Ottoman inspired--the hilts are imitations of the Ottoman style rather than the Persian style. Real kilici and shamshir usually had full tangs and sandwich grip slabs, unlike these copies, which would lower the point of balance on the originals closer towards the hilt. (As I mentioned, the Windlass "shamshir" I have has terrible balance.)

The Military Heritage version is historically constructed. Its blade is Rockwell 38 in hardness, though, which while historically plausible, is about 10 less than most reproductions these days. And as Hotspur said, it comes unsharpened.

I'm reasonably happy with my Windlass--I'm going to remake the grips some day, and regrind the tip to make some distal taper (which it simply does not have at all!) to improve the balance. The blade has held up nicely in terms of durability though.

The Cold Steel is probably your best bet for backyard cutting if egregious historical inaccuracy isn't an issue.

And the Military Heritage might really be worth it. Goodness knows it is attractive, and well priced. Frankly I'd give THAT one a try!

Good luck!
