Actually, they sent me the cordless as a substitution when they were out of this one. Love it! works great! Sharpen all my tungsten effortlessly (well, you do have to change collets) , blunts the tip, cuts off contaminated ends when you dip.

What I ordered was the "Corded Sharpie DX Tungsten Grinder" - what they sent me was the "Cordless Sharpie" - turns out, the cordless version works great and I guess I'm glad they sent it by mistake. The thing puts a very nice point on the tungsten and is consistent. The fact that it's cordless really makes it super convenient, more so than I originally thought.
