Fixed blade knives are among the coolest knives you can get — they are bad ass. But, the usefulness of them is questionable. Are they useful? Yes. Are the useful very often? Not really. ((For most people, that is.)) However, there are such things as smaller fixed blade knives, among which the ESEE Izula is one of the more popular options.
The Izula has a small, but able, 2.6” blade on it made of 1095 high carbon steel. It’s like a mini version of my favorite survival knife, the ESEE 4. And that makes it really interesting.
