      I'll admit it - wire wheels and cups scare the heck out of me. I've avoided using one for years primarily because of horror stories I've heard about these things grabbing work and slinging it across the room or into a body part, or stories of the wheels' wire ended up embedded in body parts. Scary stuff! But I do blacksmithing in my spare time and needed a better way to deal with scale removal on larger items. So I trotted myself down to the HD and gave this one a try. I have to say, I"m terribly impressed. First, I have used this quite a bit and have yet to have the first piece of wire sling off of it. Second, it does a terrific job, takes de-scaling a piece from a long job on a grinder/polisher to a couple of minutes at the MOST with this mounted on my hand grinder. Third, it is so far extremely durable, I inspected the thing just last night and it's difficult to even tell it's been used, there is a little bit of bending in of the face wires, but that's barely noticeable - the twists are intact and look like they looked when I bought it. An added bonus, BTW, it imparts an every so slight hammered texture to the steel, which I find I REALLY like - if I could figure out a way to use this on very small items I would, I like the texture so much I prefer it now. I honestly can't imagine having to replace this anytime soon, but if I ever do, I will be right back to HD to buy the same one.
