I have looked at and read about the Timberline sharpener for years, but never could lay down the money (I have been accused of throwing nickels around like they are manhole covers). I finally bought one, but it was a two step process.
First, I told my gadget-obsessed brother in law about Timberline. After he bought one, I tried his and was very impressed. So there was nothing to do but buy my own.
I am very pleased. The chain seems to hold its edge well, it is probably a bit faster than hand filing, and my perception is that less metal is removed each time. I can usually hand file a chain only about six times before I have to take it to the saw shop. I've been hand filing for about 35 years, but I think I actually have had 35 different one year experiences; I've never really gotten any better.
