i was using one as my boot knife for a long while. i replaced it with a custom blade, but not because i didn't like the mini-pitbull anymore. the AUS6 steel is not the newest or best steel out there, but it is stainless and did not rust up on me. my use was strictly as a last ditch weapon, so i didn't use it much for utility work. it is a very comfortable knife to hold, even though it is small in size. the G10 scales r secure even when wet.
for $25-$30, it is a good knife. the sheath could use some work (replaced it twice.. the clip broke off each time, and i couldn't rely on it to secure the knife to my boot... reason why i 'retired' the mini-pitbull). i like the design and it works for the role i had for it.
hope this helps.
