Serration's

[Jerry Hossom]

I put serration's on my tactical knives using a checkering file (20 lpi) to lay in the pattern spacing. I then use a 1/8" parallel round file to open every 3rd and 4th file line. The result is something more like a saw edge than a tomato slicer, but that's what I prefer in a tactical knife anyway. It takes me about 20 minutes per inch, after a fair bit of practice.

Good luck and email me if you have any specific questions.
