| 161 | Handle for a file having polygonal cross section | US760265 | 1996-12-05 | US5762344A | 1998-06-09 | Joacim Einvall |
| A file of polygonal cross section is secured frictionally in a hole of a handle. The hole has as many corners as the file, and a surface extends between adjacent pairs of the corners of the hole. Each of those surfaces includes a concave segment and a convex segment. The concave segment is shaped such that relative rotation between the handle and file causes the corners of the file to tightly engage the concave segments to secure the file within the handle. | ||||||

The cord may be a folded bungee cord, the ends (20, 21) of which are secured to holes (30, 31) in the blade by means of hooks (28, 29) on the ends of the cord. A pliable tubing (33) may contain the bungee cord ends. | ||||||
| 163 | Holder for detachable blades | US53240 | 1979-06-29 | US4261104A | 1981-04-14 | John F. Cuscovitch |
| A holder for detachable, apertured blades has two body sections connected intermediate the ends thereof for pivotal movement between open and closed positions. A blade received within a recess at one end of one of the body sections, when the holder is in open position, is retained on a projection which extends through and beyond the recess at the one end. A latching member mounted in fixed position on the other of the sections cooperates with the projection to interlock the blade in the holder when the body sections are pivoted to closed position. A detent at the free end of the handle portion of the holder releasably retains the two body sections in closed position. | ||||||
