I've used a few of the Cold Steel throwing implements over the years and I found them to be good quality for the price. I had one of their three knife sets, a couple of their throwing stars, and one of the cheap tomahawks. I honestly suck at throwing so these things got beat to hell but they held up well to the abuse. I eventually broke the handle on the tomahawk but they have reasonably priced replacements.
I will caveat by saying that although I think they have quality products I got rid of every Cold Steel product I owner after interacting with their owner/spokesperson at SHOT a few years back. The guy was such an arrogant/pompous jerk that I wanted nothing to do with the company after that. They also had a video compilation playing at their booth of said spokesperson massacring deer and antelope with a rifle, not hunting, I mean mowing down whole herds. It was weird.
I have owned a few SOG products that performed fairly well, but have never tried any of their throwing tools.
