Pat;
 As for the bridle strap tool I don't know but as for the "checkering file" I 
am of the opinion that "checkering" should not be done to hammer tails.  A 
sanding paddle, or some such, covered with 80 to 100 grit carbide paper 
should be used for best results.
  The best checking results for grand hammers comes through a combination of 
felt compaction/wire flexing/grain orientation of backcheck leather/ angle of 
backcheck/shape & arc of the hammer tail. " Roughing" the tail of a hammer, 
as with a "checkering file" does little to improve the checking of a hammer 
long term and is contraindicated for excellent checking and optimum 
performance. 
My opinion.
