My favourite small mid folder.
The Sea lion is perfect in my hand. It is the blade I play with and flip every night and use often as a gents knife and also at work. The handle is contoured perfectly to my large hands for a near perfect 4 finger grip. The rounded handle edges give zero hotspots. Lockup is solid though I did add some plumbers take to the pivot inside like I have some of my ZT's and other Kizers to avoid pivot loosening (loctite blue is another option). The blade to handle ratio is stellar. Flipping action and lockup is perfect with no blade play in any direction. I own about 35 ZT's, Kizer, Ruikes bestechs Spydercos and cold steels etc and of all the mid sized blades this by far my favourite. I am surprised it doesn't get more love. The slightly thicker blade makes also suitable for heavier tasks so it is a good all rounder. I actually swapped out the pocket clip with one from a cheaper Ruike (fenix) knife and it rides deep carry now and the blue matches perfectly. Lockup is about 50% and I have three spare stainless inserts for future of the benefits of the ZTs and Kizers replaceable inserts. Just make sure to hassle your dealer for these when you purchase. All in all I love it. I am thinking of buying a second as it would be missed if lost in the field (It happens). Highly recommended. Final note it is light and well balanced in hand and very carryable. Last time I checked I think about 120 grams. I guess if they milled the frame like is becoming more common nowadays (which I am a massive fan of) it could be lighter but the current weight is perfect for a mid sized blade IMO. I put pocket clip as a con only because I demand deep pocket carry. The original clip looks better and follows the curved design better and is possibly more comfortable on hand but the replacement clip from the $50 Ruike suits my purposes better for unseen carry. Personal preference really.
