The lansky deluxe is all you need. It's what I use to sharpen my Benchmade 940 with s30v steel. Works like perfection. Although I cannot comment on blades with harder steel (which are few and far in between.)
This.
I get my Benchmade 940 with s30v steel to shave hair and Slice through phone book paper with ease. Takes about 15 minutes. It's all about sharpening your blade at the angle your blade is set at.
I use the 16650's in my FourSevens QT2L-X.
Initially I thought it would be a sweet light with my rechargeable Nitecore RCR123 650mAh batteries. Quickly i realized that 2 batteries in series do not double the mAh, just the volts.
2,500mAh KeepPower 16650's do it proper justice.
Thanks for the info! Hows the fit? Does this 16650 just drop in, or does it need some persuasion?
i am really excited to have a single-cell solution for my QT2L-X :)
