It probably works great if used properly. I put it on the Work Sharp, a blade sharpener, and didn't think about it. I had to remove the blade guide and just use the downstroke side. However, I also used the spread side and quickly made thin latigo strips out of it. Damn. I've been wanting to get another one so I can use it properly, but haven't had the time yet. I used an old straight razor I found at a thrift store.
