I purchased a pair (JIS # 2 and JIS #3) Vessel Impacta screw drivers from Japan (on eBay) and they arrived yesterday. I've used them both yesterday and today on some very difficult, tight and rusted Philipshead and JIS screws.
I found them really excellent quality, very hard tips and great not to have to go find and use the 'regular' impact driver - which I often find difficult to line up and find space to hit or whatever.
These screwdrivers have the 'undo' function built in: you just use them as normal but when stuck, you hit the end with a hammer. The spiral cam inside will then turn the blade by 12deg per hit. So usually one or two hits is enough to loosen the screw, without changing tool.
