I got the grinder on sale a couple of years ago for $105.00, very handy but their asking price is way too much for what it is, IMHO.
grinding ugh.....I started a Bowie and ended up with a letter opener.
Another thing I learned, don't work the steel cold. I bent the butt end up to hammer between the 2 tails and did it when it wasn't hot enough, take a look if you click on the pic after it is up you get a close up, also tried to drive a drift thru that hole to make it larger and it cooled the steel very quickly, and cracked it. I guess that little bit of carbon makes a big difference, seems mild steel is much more forgiving.
