I suggest you jump on those swimming pool green wilkins grips asap then because according to Wilkins, the material went out of production and there very well may be no more of them ever made. Once they're gone they're gone. I missed out on a set of minis and have been kicking myself for it. That said, if you don't mind a bit of wait time, cuscadi does some spectacular work and since they are truly custom, you can choose from a nearly endless set of material, milling, and finishing options. Either way, custom scales really transform the griptilians into an absolutely world class knife. The standard scales are fine, and the noryl gtx handles, while cheap feeling, are actually very tough and durable, but a grip with m4 and custom scales is in another league.
