## Questions & Answers

**Q: What's the secret to removing the old blade and inserting a new one?  Does it slide in and out from the back end?**
A: I've never had to remove the old blade and replace it. I just use pliers to snap off the dulled little piece which reveals a new, sharp edge. Once the whole blade is used up, I usually just toss it. I don't know if it's replaceable or not.

**Q: Where can I get replacement blades??**
A: hardware store,  walmart.

**Q: What do you do when it jams after you replaced the blade? This didn’t happen the first time I replaced the blade**
A: Just take it apart and clean it with soap and water and a small brush (like a toothbrush). This is a precision made tool, and by and far the best in it's class I might add. The specs are tight, so if a little debris (such as dirt or pocket lint), gets into the sliding track grooves, it can block the blade from extending. Remember to air dry the parts separately before re-assembling. With proper cleaning and care, this high quality, heavy duty tool will dutifully serve you for a lifetime. I keep this very model on me at all times (L-500GRP).

**Q: Does it have a belt clip?**
A: No.

Sharp blades, nice feel. I like the enamelled aluminum body with rubbery grip, holds up well to abuse. Somehow the blade stays where you put it 95% of the time despite not locking. Very convenient.
