Shortening plastic key tops

[Stéphane Collin]

Hello Alan.

I guess I have to improve first my sharpening method for my chiesels.  I 
chose to shorten the front side just because I found it that difficult 
to cut into plastic neatly, while my attempts to make a nice rounded 
shape at the front with a file was an immediate success.
What angle are your hand chiesels cutting edges ? 20° ? even less ? My 
finest are 25° and I found it unpracticable.

Thanks for your input.
