I have been working in the field running a skid-steer, brush hogging, and building fence the past 9 weeks. I primarily carry in heavy work pants the ZT 560 Hinderer. It is a big knife but has titanium scales so that cuts the weight quite a bit. I do not advocate abuse of a knife but I regularly use to pry, cut, wedge, etc. Have cut light wire with it and used to pry saplings jamming up the high-flow rotary cutter when too far afield from the tool truck.
After I bent out the pocket clip I went to my more normal carry, the Benchmade Torret. Much thinner blade but is an excellent farm/ranch/hunting pocket knife as well. Thinner blade great for breasting ducks, geese and turkeys in the field, cleaning small game and general carry. It is a liner lock and that is the only issue I have ever had with the knife.
Had gotten water in the jeep cab in a deep crossing and was trying to pop/pry out the floor plugs to drain the flooded floor board. Sediment in the muddy water had become wedged between the liner and the frame/scales making it impossible to close. I could not tap or blow it out and had a fixed blade knife, when I needed a pocket knife, for the rest of the day (simply had to throw in the glove box because had no way to carry). Blew it out that evening with the compressor and it was as good as new. But I did start being more careful with submerging a liner lock in muddy water.
Then I bent the pocket clip on the Benchmade too! Went to a little automatic I had with me--a Piranah DNA. Frankly it has served admirably in hard use. I had to cut a piece of hydraulic hose with it yesterday and it did fine. (I just noticed it still has grease at the base of the blade from the pinched hydraulic hose). It's not a pry-bar-like ZT, but I would rate right with Leek or any other quality knife that one would (and should) use in accordance with the owners manual.

BUT I'll that a Leek over all ZT's anyday
