“Our brass CT Finger Planes are made following the old Gewa models that are now unobtainable. The same in size and shape, the only difference is the blade lock which, instead of being a wooden wedge like the originals, is a tilting brass one with a locking screw. This ensures better stability and easier adjustment.”
