    Car Battery Power for Hooking up Lights and laptop, any suggestions?

    An APC UPS is a seriously expensive way to do this, on a per-joule basis. More economical (and giving you WAY more stored energy) would be a deep cycle battery and an inverter. If stored and used indoors, you definitely want a sealed (AGM or gel cell) battery. A "size 24" 70-80Ah battery will...

    NiCad or NiMh for cordless leaf blower?

    I agree that NiMH is superior to NiCad for almost all applications (and the environmental / disposal issues are significant here), but as of a couple of years ago (when this was last an issue for something I was designing) I needed a small rechargable battery that could work efficiently at about...

    NiCad or NiMh for cordless leaf blower?

    A leaf blower sounds like a high drain device. How many amps does it draw? If you're draining at a high rate, NiCads (even of lower capacity) will actually provide greater capacity than NiMH. NiMH does not work well for high drain loads. HCaul

    Surefire Knife

    Thanks. Did you ever sharpen/hone it? How easy is it to maintain the edge on the SF steel? HCaul

    Surefire Knife

    Huh? I have no contempt for SF. As I said, I own many of their products and I am seriously considering the Delta knife. Sorry if something I wrote could be interpreted as contempt (can you please quote what it is that makes you think I feel that way?). I do worry about SF being regarded as...

    Surefire Knife

    I'm not assuming they're unreliable, only that I'm unwilling to let Surefire's reputation for good flashlights color my expectations too much in this new and somewhat different domain. Also, Surefire seems to get a bit of free pass for some of its mistakes for some reason, and the reliability of...

    Surefire Knife

    Wow, that's an extraordinary claim. So I should just assume these knives are going to as reliable as, say, my (proven trustworthy) Sebenza, even though SF's reputation is primarily outside the knife trade, even though these are relatively new products without a lot of experience behind them...

    Surefire Knife

    I'm suggesting only that the Surefire "brand" should not be regarded, in and of itself, as automaticly implying reliability. They don't have magic powers in their manufacturing or R&D, nor are they incapable of producing an unreliable product every now and then, be it a flashlight part or a...

    Surefire Knife

    Why are the tailcap switches exempt from that "reliability" stuff? Wouldn't a good time to have made them reliable been BEFORE incorporating them into half their product line? Sorry, I like many Surefire products, and I own a lot of them, but they aren't magic, and their recent track record...

    Surefire Knife

    Then I wonder why they can't seem to make a reliable tailcap switch.... Seriously though, I'm actually interested in the Delta knife (I really like the built in slotted wrench) but I'd be curious as to what those "advanced processes" are above and beyond standard precision metalworking. HCaul
