Chainsaw Sharpener Jig Kit, Portable Chain Saw Sharpening Tool with Burr Grinding Stone, Chainsaw Sharpener, Manual Chain Saw Blade Sharpener Attachment for Electric/Chain Saw, Lumberjack

I know some people like to sharpen the blades on their chainsaws the old-fashioned way with a chainsaw blade file and that's okay, the only thing is, you've got to know what you are doing, if you get it wrong you cold actually make things worse, and ruin the blades performance.This little device by Funnytek takes all the guesswork away, and once it set up correctly on your saw, it is actually quite a simple process to get your blade working as it should once again. It's just a matter of carefully reading and following the instructions.

This product doesn't work, don't waste your money

I liked the idea of having a jig to ensure I was at the correct angle when sharpening and this does that.It is a bit fiddly to set up and attach but once on it works pretty well.My chainsaw was definitely blunt and it was struggling to get through medium diameter logs that it would once eat through easily. I have sharpened it now using this. It is a fiddly and time-consuming process and you need to do some research and find some instructions to know what you are supposed to be doing! But this definitely helps simplify the process a little.

very fiddly to fit and use
