I have really taken a liking to to Japanese stuff. I wish I knew about this stuff when I was working on motorcycles alot. Especially the #2 cross jis screwdrivers.
I have a framer. Great gun, batteries are expensive. I'm getting ready to do some privacy fence and it works great for putting up the pickets. Take one apart and do the the cleaning in the manual if it doesn't work right but I bet they work fine.
