Some people have said that certain plastics hold up better in cold weather. I use a variety of wedges, and re-condition them when damaged.

- I cut the damaged tips off with a bandsaw (hacksaw, or any fine tooth saw would work);
- Form a new bevel / taper with the belt sander, and re-shape any damaged parts;
- Cut off any 'fuzz' that forms with a sharp utility knife - the thermoplastic wedge material gets soft (and hot!) when sanded;
- Square the end with the disc sander;
- ***Form the final edge bevel by sanding
into the wedge***. The thermoplastic material will melt back into a smooth, solid bevel, instead of forming a goopy, fuzzy, soft mess at the end.
