I had some free time, so I'm listing this for the first time in three years. The strength and durability are not a problem due to the stainless steel welding, but the appearance is poor due to simple rust prevention. The hook tip width is 7mm, and it can lift up to 100kg without any issues. The screw part of the gaff is the same as the handle of a landing net, which is 1/2 inch.
