This knife is terrible. It was cheap, so I should have been dubious about quality. Save your money for a better knife since you can easily cut yourself with this knife. It's made of cheap plastic and soft metal parts, so don't count on the blade locking properly. It's an insult to even have a fire fighter logo. Don't make the same mistake in buying this poorly constructed tool.
Negative
