Well, I sent the link to my son and he told me he would buy it for me since my Dave thought it was too expensive!
Besides, he'll get good use out of it since where I'll use it will be on his farm!
I could use it tomorrow though, so I guess I'll have to see if we can use the grinder on one of the old ones until it arrives. I'd better go back and look at how to sharpen a shovel.
