With such an extremely narrow handle one could imagine that lock strength would be an issue. Fortunately, Spyderco has its Compression Lock that overcomes any qualms concerning weakness. The action is smooth and easy. The lock-up is rigid and crisp without a wobble or flex. Closing only requires a modest squeeze between thumb and fore finger, and a roll of the wrist to close the blade with a positive detent.
The modified leaf blade is well proportioned and strangely balances itself with the rather slender handle. The full flat ground VG-10 blade is a proven cutter that will take and hold a razor sharp edge, while requiring minimal attention on the SharpMaker to re-hone to shaving sharpness. Black G-10 creates a positive grip especially when combined with the blade’s spine jimping. Open construction is accomplished with two barrel spacers, a stepped thong hole liner and inset stop pin. Liners are skeletonized to reduce weight but maintain strength. My only query for Sal is why the Japanese maker (presumably G.Sakai) used nylon bushings rather than the currently preferred phosphor bronze.
Pocket carry is accessible by the use of a tip-up wire clip that allows for right or left hand carry. My only modification would be to perhaps switch the standard wire clip for the deep-pocket-carry clip as found on the Caly3, Caly3.5, and others.
Functional, aesthetic, ergonomic, solid, and minimal are all words that a thesaurus would use to describe any Spyderco, so it does for the C150GP Junior. Thank you Alexandru for this latest Spyderco; may your son continue to be a muse for your creativity.
