Query: Lock Broke first month, waste of money ...............

I have two SOG Trident knives. Both were a disappointment. Quality parts yes, but poor function. Here I was carrying a Trident camo version in my pocket for emergencies. Well one day, I went to check the blade opening and the damm thing would not open the lock was broken and very loose. So goes for confidence and security. My other Trident openned hard and hardly closed. What a waste. I will be staying with Cold Steel, Gerber and my fav for quality - Kershaw. My Kershaw does not have all the fancy locks to screw up. It has worked fine from day one, quick openning via thumb stud and easy, secure closing. It is tough to become dissappointed in a brand name like SOG, BUT MY LIFE MAY DEPEND UPON MY CARRY KNIFE . (also it is GIBB'S rule #9)
