    I'm looking to have some knurling added to a set of darts but I need the flat style in Figure 1, below. In my experience I've only been able to find people who can do the other, figure 2, diamond style. (I posted both the thumbnail and the full image cuz the thumbnail is kind of hard to see.) Does anybody on here know anyone who might be able to do that for me? Thanks!

    I suspect kennyG will have some input for you here. If he gets dug out of the snow!

    I'm sure someone who does custom work can reproduce that. If KennyG pops in he can reply as he's playing with some dart designs himself and has the lathe to make them.

    Interesting what may be going on is they are really not fully formed knurls . Knurls are made with a form tool vs a cutting tool so pressure dictates how raised the diamond pattern is. By adjusting the pressure on the knurlers one should be able to create you are looking at. I'll give it a try and post a pic. It shouldn't be that difficult.

    had a little shop time today so I took a piece of scrap and I think this is what you want. This is a piece of scrap mild steel doesn't machine well but you can see the gradation from fully formed knurls to the partials. In the machining world that is not a quality they like.

    And all this time I assumed two distinct tools were responsible. Goes to show what I (don't) know about machining! I've seen that not-fully-formed knurl on several dart models made in England, and it definitely works better for my grip and throwing style. Thanks Kenny, sounds like I might be able to get anybody with a knurling tool to do it for me, with a little practice at least.

    @DDBuckshot it kind of depends on what the material is i.e. tungsten , brass, steel and it will probably require some sanding. I would offer to do it but not on a set of pre-made darts. Knurling can be kind of touchy and if it gets started wrong there is no going back. If you go to a machinist figure at least $80+ . Your best bet would be to find a hobbiest locally. may have a local member willing to try.
