Tandy Fine Diamond Chisel

[Hi Im Joe]

You are thinking of teeth per inch or prongs per inch or w/e. If you have 8 prongs in an inch that means you have seven spaces between the prongs (aka stitches). Which would give you 7 stitches per inch.

ok-- so my statement was correct

[Hi Im Joe]

There is no standard measurement. All the companies seem to do it a bit differently. You have to find out exactly what they are measuring when they say 3mm or w/e.

According to my local Tandy, these are the stitches per inch of the older "standard" crafttool diamond chisels and the new Fine Diamond Chisels:

STANDARD DIAMOND CHISELS:

• 4mm - 4 stitches per inch
• 3mm - 5 stitches per inch
• 2mm - 6 stitches per inch

FINE DIAMOND CHISELS:

• 3.5mm - 7 stitches per inch
• 3mm - 8 stitches per inch
• 2.5mm - 9 stitches per inch

Has anyone else tried these chisels?

I grabbed the 3mm 9-prong (88056-09) to play with. The handle feels nice but the prongs are so coarsely ground that it's like stabbing the leather with a barbed spear. It works, but the rough texture on the prongs makes getting the chisel in and out of the leather harder than it should be. I felt like I was spending as much time wrestling the chisel out of the leather as I spent actually stitching my test pieces.

I have been using the 2.5mm on all of my wallet interiors and other fine stitched areas and a fine waxed thread and just love how much better it comes out. In fact, I have been double stitching the fine areas and it comes out really balanced. It is also the perfect combination (the fine stitch and fine waxed thread) for all of those out of the way/hidden stitched areas (such as the pocket bottoms when layering the pockets).

The inner stitched lines of the card pockets are done with the 2.5mm chisel and fine thread (double stitched).
