On second thought, the other option besides knurling could be to add a lanyard loop like on the battery in the mini kit I just got. It would be both functional and convenient, giving a space to use for gripping and also keeping the pv much more vertical when used on the lanyard, something I prefer.
Does anyone have any suggestions for how to get this adaptor off for refilling, besides carrying around my nubby silicone pot holder?
Hey AG, is this something that can be engraved? I'm not much for artistic stuff, considering I'm hopeless with it, but I may break out my husbands dremel to see about adding some texture if you think it could be done.
