Stanley Surform 5-1/2 in. Pocket Fine-Cut Plane Blade Replacement for 21-399

New replacement blades fit my very old plane perfectly, they are very sharp and have done the work I needed them to do.

Handiest little tool in my shop!!!

was exact replacment part

great tool for drywall, works to give you straight clean edges,

This is the sharpest blade for plaster finishing and leather-hard clay if you want a good sculpting tool . I use the long flat and the half round and the short flat . It was designed for wood I think and fits any handle. It is used every time a mold is made at Schaefer Art Bronze Foundry in Arlington Texas. There is no substitute for this blade. It lasts sharp for a long time. Be sure to also get a file cleaning wire brush and dry it when you clean up so it will stay sharp.All the edges were cleaned on these plaster mother-molds with a Stanley Surform blade before they were drilled and separated from the urethane rubber on this giant head.

It worked as expected.

We use these on raw ceramics and forming plaster models. They work great, Wish they lasted a little longer. But our use is a little abusive. With wood they last a quite bit longer.

Works as expected.

I received the item on time and it works great. Thanks

Great! Exact replacement part.
