Its no longer a chore to sand my metal. These things are getting more difficult to find. I've profiled 10+ knifes nonstop and never had any issues. Would have given 5 stars, but only used it for a day. It is light enough that I did hours of sanding one handed.

3M 28366 Final Thoughts
"It's definitely come in handy."
I bought this sander to sharpen knives, chisels, and plane irons. These things are getting more difficult to find. Of course not, but it comes pretty close for a lot less. Otherwise it will hold up just fine for most usage. After some research, I decided to give it a try.
