Thank you both for your response!
I have had my first 11-4 since I was 16 which makes it 19 years old. I also started as a volunteer firefighter that same year and I have using that same 11-4 since for firefighting, as well as camping, opening boxes, cutting rope and other every day needs. Kind of extensive for this blade but it has held up very well! Just got my knife & new sheath back from Randall last week actually.
Shelley you are right about needing to sharpen the 01 blade a lot as with all of this work it does dull fast.
