I wish I would have bought something like this a few years ago! I've never had one because I've never had to cut too many grooves and when I have I've always settled for a regular chisel. I then decided to update my store, starting with a few simple cabinets. The first tier includes 6 doors - a total of 24 slots. I started doing them the old way and quickly realized what a huge pain it would be. This baby helped me turn them off in no time. It's best to give yourself a project in the shop to get comfortable before moving on to the finer work. It's fairly reliable, but there's still a learning curve on how best to hold it and how to align it properly. I chose this one based on the great reviews and the fact that it's made in the USA.
