Anyone out there with one of these spring assist models. Was at Bass Pro nearby last week and spotted two or three different models. One had a drop point blade priced at $49 and the other had a straighter blade. These models have aluminum handles with a glass breaker stud at bottom of handle. Believe the blades are 440 stainless. Got a Sog Trident but may add one of these to my collection. Just wondering about overall quality.
