Buy something else first. As you can see from the picture the quality control of this item was not very good. The tip was tacked using an offline tack. The head is not in line with the shaft. Second, a short thumbscrew. It is very difficult to hold back and turn around. The slotted latches on the included blades are wider than the blades so they only hold one side of the blade. I could tell you more, but save yourself the grief and move on to a better subject.
