I've been using the Reylight Pineapple Mini since I got it a while back. It has come in handy during multiple power outages and server maintenance weekends at work.
It's titanium, and can either take a rechargeable 10440 lithium battery, or a standard AAA.
I think its hard to beat a pinapple mini. I like the texturing on yours.
Thanks! I think the seigaiha pattern was a limited run?
I think you are right. It looks better than the typicalgrenade style.
