Kershaw Concierge in stock
Handle material and blade finish, not steel. Both use 8Cr13MoV stainless. KS4020X has a titanium-coated blade and a black G10 handle; KS4020MIB has a stonewash blade and a brown Micarta handle, and adds a keyring where the other has a lanyard hole.
Both run 8Cr13MoV, so edge retention, corrosion resistance and sharpening behavior are the same. This is a comfort and appearance decision rather than a performance one.
Both are 4.25 inches closed with a 3.25 inch blade and an extended tang.
G10 is harder and more aggressively textured. Micarta is warmer, softer to hold, and gains grip as it wears in. Brown Micarta also darkens over years, which some owners specifically want.
Blade finish differs too: titanium coating on the G10 version, stonewash on the Micarta one. Coatings add a little corrosion protection and wear off at contact points over time.
The third Concierge Micarta in the range, KS4020MCG, uses D2 rather than 8Cr13MoV. See the two Micarta versions compared.
All of these are closeouts, so availability is finite.
