I am interested in purchasing a tungsten sharpener, actually an Arc Zone sharpie, I did a search and read all the posts and it seems to have allot of mixed reviews,

1. the motor slows down considerabilty while sharpening?

2. the grinding lines are not perpendicular to the tungsten more of a swirl effect because of a small diamond grinding wheel?

I really cant justify the cost of a Piranha and others like it for the amount of welding I am doing right now, I have been grinding my tungsten on a grinding wheel and I am not happy with the quality and consicestents so please if you have a Sharpie or used one please let me know what you think of them.

Thanks Dave
