Haak anatomy en haak type
Let's look at a hook, and try to put the right terms on the right parts. This picture shows a hook (note that it actually is a rare vertical eye hook, great for this purpose).
The letters represent:
A - Eye width - a good measure to use when indicating small distances in the pattern, especially in the front
B - Overall length. The hooks 'outer' horizontal dimension
C- Shank length. The length of the part we normally tie the fly on
D - Bend - it can be difficult to determine where the shank ends and the bend begins, especially on curved hooks.
E - Barb length - sometimes use to measure out tag/butt placement on salmon flies
Gap (or sometimes gape) - almost the same as the hooks' overall height
