Kunz Adjustable Spokeshave

My flat bottom keeps clogging between the sole & cap. Cuts fine until it clogs, which is about four or five passes. I've removed the paint on the front face of the cap but that hasn't helped.

I have both the flat-, and the round-bottom version. They adjust easily, and everything works as it should. The only thing I did to make them better was to smooth the bottoms a bit, and round off some of the sharp corners on the cast iron. For the price, I believe they are really quite a good deal!

I own both of these spokeshaves for years. And I also own the Stanley equivalents. All of these require an initial setup that is routine with any new plane that isn't a rich man's toy. They work brilliantly. Highly recommended.

I own these two Kunz adjustable spokeshaves. They are copies of the Stanley Nos 151 & 151R. Compared to vintage Stanley originals, these alleged German made copies are a disappointment. The lever caps are made from significantly thinner stock and don't appear to fit the casting very well. Also, the lever cap screws aren't as robust as the Stanley originals. The sole on the flat bottom version is an oblong oval, because of the castings poor symmetry. As expected with any low cost tool, they require time consuming fettling and filing of the castings. I wouldn't buy these again. They are something you'd expect to find at Harbor Freight. If you want a good No 151, find a clean vintage Stanley original and invest your time with a better example.

I have both the flat bottom and the round bottom shaves by Kunz. The flat bottom is decent, but the round bottom just doesn't work. I expect to have to tune and work on inexpensive tools and I have spent hours working with the round bottom, but even at it's best the shave chatters even with the tiniest curls. I think that the radius of the sole is too tight and the front part of the sole isn't large enough to adequately stabilize the shave and the blade. The rounded nature causes the shave to lean forward which raises the angle of the blade. It's possible I got a dud, but I really worked the tuning process. I flattened the bed, removing the paint. I smoothed out the mouth. I reshaped the back and front of the cap iron to make sure that a perfect match between the blade iron and the cap iron. I sharpened the blade so that I could literally shave hair off my arm. It is possible that I am just doing something wrong, or that my technique stinks, but I have exhausted the possibility of this ever being a tool that I use.
