For a few years, not sure how many, my Spyderco Military was my perfect folder and as such, it was my constant companion. I had never found anything better for me......until.....I decided on buying my first Sebenza(Large Reg) and now the Millie just sits in my gear bag.
The Sebenza may seem too overpriced for some, but after carrying it for a few weeks, IMO it is well worth the money. The beauty of the Sebbie is its' simplicity of design....less parts, less things that can go wrong. The best feature of all though is the ability to completely dissassemble it for cleaning/maintenance and not void the warranty.
Could the Sebbie ever be replaced with another knife, just as the Military was? I honestly don't know. However, for now this knife is my Excalibur.....
