B
Bowie blade / Bowie knife
The Bowie is a style of knife made famous by Texas hero James Bowie. Commonly, the term refers to a large knife with a clip point blade and crossguard.
D
Damascus steel
Named after the Syrian city of Damascus. Two main types exist: Crucible Damascus ("Wootz") and pattern-welded Damascus. Wootz is a single metal whose pattern comes from carbide (specifically Cementite) banding; pattern-welded Damascus is folded and forged from two or more steels. The Wootz method was lost for centuries after being supplanted by pattern-welded Damascus due to its superior purity and performance until Dr. John Verhoeven rediscovered Wootz in the 1990s. Both are outperformed by modern steels and used mostly for aesthetic purposes today. 
DLC©
Diamond-like Carbon. A wear-resistant, low-friction coating made from tiny carbon structures in the nanometer range that are as hard as diamond. Unlike common PVD coatings, DLC is non-porous, so salt water cannot ingress.
F
Finish
Surface or surface treatment.
G
Rough Grip G-10
High-pressure fibreglass laminate composite, similar to Micarta and carbon fiber. The structured surface from the fiberglass fabric provides excellent grip.
H
Hardcoat anodization
Special variant of anodization producing an even thicker, more wear-resistant layer on aluminium.
HRC
Rockwell C Hardness Scale. Determines hardness by measuring the penetration depth of a diamond cone pressed into the metal under specific conditions.
K
Kalgard©
Blade coating process first used by knife maker Chris Reeve in the 1980s. Applied as a varnish on a sandblasted blade, then cured at 160 °C, creating a homogenous low-friction, anti-corrosive layer.
L
Liner Lock©
Named by American knife maker Michael Walker. A liner under the handle scale acts as a spring; when the blade is opened, it moves behind the blade tang to lock it securely in place.
M
