I purchased a used 2010 S30V Blk G10 and was impressed of this type of slip joint how it has a good hold in open position small thin a good full flat grind blade ergonomically good to hold my opinion is this is the best on the market I went to purchase a second through The Knife Center Spy27 BlueG10 at a sale price and waited for a few months for it to come in stock worth the wait

Pros: Blade Material, Blade Sharpness, Handle Feel, Overall Quality, Pocket Clip
Cons: None
Very good quality
This is my first Spyderco and I see the hype now. It came a little stiff out of the box, adjusting the pivot helped a ton and now it’s like butter. Finished and put together super well, scary sharp out of the box. The Spy27 has not rusted after a month of use and carry, even being in a humid location. The G10 is a little grippy but not too rough on the pockets. The design is well thought out, since you cant close the knife on yourself with your finger in the choil. The only complaint I might have is the screws + pins on one side make it difficult to disassemble but its a slipjoint so not a huge priority.
