uuuuuuuuuuumm......
gerber camp ax. thats the one that comes immediately to mind. i sold it for very, very little money because i couldnt bring myself to sell something i hated so much to anyone for more then 10$. it came with a nearly unusable edge, really, really, REALLY thick, and even as thick as it was it immediately mashed and rolled and readily took heavy damage that couldnt easily be steeled out. in order to grind that thing down to usable, it would have taken an hour at the grinder.
the head to haft connecting point readily took wood chips and any other particulate mater that passed by it. the edge of the plastic had so much crap shoved under it... i hated that thing.
wasnt to fond of the swamp rat bandicoot iether... really thick design, generally not a pleasant knife for me to use. nor was the swamp rat shaker... cut myself twice becuase my hands were covered in buffalo wing grease, and there isnt any kind of gaurd on it. that was the knife that made a gaurd an absolutely requirement for me (being that at the time i worked with food all day, most of it greasy).
the busse 3rd gen public defender came to me in an unusable state. the factory edge could not cut fabric or paper. i couldnt cut anything. yet - it could shave. the angle on each side was above 55 degree's, combine to something like 110 degree's, fatter then a square. the front section as even worse. when regrinding it down to 40 degree's on the front portion, or over took about 70% of the initial main grind. it took me something like 36 hours total to regrind the edge using an edgepro apex model. once it was ground down it was great, but its been the same with almost every busse i've gotten thats not a chopper. the edge is obtuse with a high, highly polished cutting edge - but only at the very cutting edge. so you get something that will shave, but is of terrible geometry.
all of that was bypassed with sharpening, and the pd becaume a fine knife. didnt like the tanto shape, but thats a general design flaw. that initial edge was really really terrible though.
lol... my masters balison is pretty bad too... within 10 minutes of flipping the handles are just on the verge of flying off becuase the pins have unscrewed so far. but it is masters cutlery...
