Truly hard core Japanese tanago anglers grind down the points of their hooks with jewelers' tools and microscopes so that the hook points are short enough to fit in the mouth of an extremely small fish.
The Owner Migen tanago hook was created to eliminate the need to grind down hooks. The hook point is less than a millimeter long, and is even shorter than the Gamakatsu "Ultimate."
I see these hooks as a specialty item - a niche within a niche. Even for most micros they are actually a bit too small. These hooks truly are for the smallest fish, the ones that will fit on a penny.
The hooks are snelled although they are snelled to thread rather than mono. The snells are about 1" long and end in a loop for easier attachment to your line or tippet.
