I was a little disappointed with the taper tool. I started with the 11/32 attachment, I realize that i might have to sand some of my bare shafts just get the tool on the arrow but I hand to sand considerably to get the tool on 100 percent of my Sherwood shafts. If the arrows are finished and you have cut them to length you wont get this tool on unless you sand through your arrow finish to get it on, also the blades are nowhere near as sharp as my 9 dollar bear paw taper tool. you will have to lube the hell out of your taper attachments to get them on as well. you will still have to make sure your tips are straight when installing cuz they could still be a little crooked. when I built my 5/16 shafts the tool fit all 100 shafts nicely but still cut hard with the dull blades. I realize a tight fit is going to give you a good taper but you still need to correct your tips for straightness and that's what I do with my bearpaw tool. Its fancy design looks nice but because you cant correct a finished arrow it creates a lot more work for you with no benefit at the end. stick with cheaper ones and save your money for more arrows.
