All of my stippling/texturing is done with a power/rotary tool. Specifically a GRS 850 tool.... Turns at 400,000 rpm, and using 1/16" shanked burrs (dental burrs). I use burrs of various sizes/shapes to achieve my desired results. The latest version is:

Another, lower cost option is:
http://www.turbocarver.com/ These are the best tools for the job. Many will say, "Get a Dremel"..... DO NOT! At least for this purpose, It does a very poor job at best....and any of the slow speed/high torque tools biggest problem with stippling/texturing....
Listen carefully!! These type grinders, along with dremels have a BIG problem when used for stippling/texturing..... they have a lot of torque. You can be going along, and all of a sudden they will "grab", and drag the turn burr across whatever you're working on! Causing an awful train wreck!
A cheaper option is
https://www.harborfreight.com/pneumatic-18-in-micro-die-grinder-kit-60244.html but it still has the issue listed above.
I've tried doing it with a hand held "blade" which is shaped somewhat like a tiny spoon, but you are talking DAYS to stipple/texture a single handle, and it's not an option when working on metal.
With texturing on materials other than metals, it requires removing material to achieve the texture.....with metals, it can be done by "moving" material....what that means is that a hammer/punch combo isn't really an option.
I do like Blackwood. Here's a few examples.....
On Fossil Ivory....
And on Titanium....
