    ordered a great new file for jimping. It's a checkering file. Ebay.com was the best price and fastest shipping time i found for this particular brand. Grobet Swiss made files. Works great and reviews say this brand is the best for the job. Nice even jimping with a few strokes. [​IMG] [​IMG]

    I have looked at these files before but never actually ordered one. It looks like it does a nice clean job though. Just as a side note I would be cautious about those two big holes between the ricasso and the first pin. There are two possible issues I see. Firstly when a knife is abused or flexed hard, there is a great deal of force concentrated on that area which could snap it due to the amount of material removed. The second possible issue I have seen myself, in fillet knife testing. When the knife is flexed hard, the flex wants to continue throughout that area back into the tang, and not just the blade. What this leads to is scale popping. Essentially without a very strong mechanical connection like a corby bolt, the epoxy can fail during the flex and the scale fronts will pop loose. Epoxy is strong stuff and a peened pin helps a lot, but the leverage created by the flex is also very high. Not saying anything bad WILL happen, but just something to watch for in the future.

    Ya I got a. It carried away. Normally I'd step down a couple sizes there and leave the post between the two holes. This knife will be for slicing only as the guy extplined and the 10" Seax chopper he wants as the combo will be for heavier work. So hoping it will be ok. Thanks though, something to remember for the future and to improve on.

    Maybe if I braze the front there if it would strengthen it a bit.

    Jmho on checkering files for jimping. The one in your pic is smooth on both side edges of the file
    They are also available with one side that cuts and one smooth side. The small cutting face on the side is very handy for filing slight curves like on a top curved thumb rest. You can make the corner and keep the lines even. The wide flat side doesn't make the curve very well and can mess up your pattern.
    Its just something to think about if your ordering. And yes as usual I did find out the hard way.
    If anyone is interested there is a guy on ebay selling grobet checkering files all the way down to 000 in size. ( 00 = 20 lines per in ) Here's the link https://www.ebay.ca/itm/130860813597?var=431435897438
