Man I love this thing already. I have a small shop in my garage and the bench grinder I have only has one wheel on it. I’ve used this thing to sharpen my electrodes and it makes it a more consistent taper and doesn’t leave the grind marks that happen with the bench grinder. I wish I had more TIG Work to use it more. For now it’s just keeping my skills up.

Decent little grinder, guess I will see how long it holds up. Would of given it 5 stars but since I haven't had it long enough to see the reliability that's why I gave it 4 stars.

I just received this Sharpie and think it's just great. It will sharpen the tungsten fast and accurately every time. No more contaminated tungsten's and no need to have a dedicated bench grinder anymore. This unit will cut the contaminated tungsten and sharpen it fast. Spending the extra $'s for the Deluxe model was a wise choice as well with the extra grinding wheel and storage case. The unit is built very well and runs very smooth plus it has a variable speed adjustment and a trigger lock.If your trying to obtain the perfect Tig weld this is a must have and this is absolutely the right place to buy it.
