This tool is in my tool kit on every house I flip. It never gets clogged, it fits in the smallest of places but what I like best is it works on both sides the same time. I don't have to FlipIt when working in tight places.
I have had one of these Shinto rasps in my tool collection for 8-10 years now. Just as many specialized tools have a unique application, when you need to remove material rapidly, it is fantastic as it does not clog up as an ordinary wood rasp would. Leather glove hand protection is helpful as the teeth are very sharp and it is sometimes helpful to hold the front of the blade for finer work! It is a great tool!
I have recently bought this Shinto Rasp and it has proven its self worthy. This tool is well worth the money. Unlike other rasps that get clogged with wood shavings, the Shinto rasp NEVER gets clogged. Think of it as a band saw blade that has teeth on both sides one fine and one course and shaped sort like a honeycomb. When you want to switch from coarse to fine the rasp can easily become detached from the handle and switched around. It works great for shaping legs that are a Queen Ann style furniture, something you cannot turn on a Lathe but still needs to be round. The Shinto rasp has definitely earned a spot in my shop.
I've used a sure form for years which can make a mess, large rasps are better, which use mostly, Iwasaki rasps too fine. the fine side is impressive having 8 saw blades has little tear out. takes some getting used to, but I think the coarse side could really hog out some wood. Used it on all the corners on 1/4" plywood boxes.
This tool works very well. Would have given it five stars, but I wish it were larger! Also, I would have preferred that the front grip were adjustable, or farther up and forward. Many others mentioned that they don't use the handle at all, and I may try that.
Used the rasp on some downed wood my son brought from the forest. He is making a rough table from it. The rasp didn't have any trouble at all with the green wood, and smoothed it nicely.
