I have had:
Ninravus Cub
Snody Gravitator
940/941
Grip 550HG
Mini Grip 555HG
Mini Dejavoo
527 Mini Presidio Ultra
I do my homework before buying a knife, so I have not been dissapointed with any of them really... the only exception would be the Dejavoo's closed retention. I seek out many many pictures and take each review I can find into account. There are things I like and don't like. I would say I don't care for MOST Benchmade OR Spyderco designs. That is, for me, they leave something -to- a lot - to be desired. For me, this is mostly atheistic. I don't like either of their standard clips, especially the black "painted" ones. I don't like complicated designs. I don't like bells and whistles.
The only BM I still have is a Mini Grip 555HG. It is just a great all around *small* knife. The size is great, BM does a superb job with the Heat Treat of their 154cm, the grind is ideal for a cutting tool, the hole-opening is perfect, the fit and finish is spot on, the action is great, the AXIS is a fun, very functional system, the weight is a breath of fresh air compared to many other options, it is fully ambidextrous, and FRN is a fantastic material (heat resistant, cold resistant, basically chip proof, and almost self-healing).
Personally, I would recommend a Mini Grip (555HG of course) or a 940 (gorgeous, simple design, slim, lightweight, S30V, and drips with quality).
