From a personal perspective don't waste your money on a mora crook knife...
Mora make fantastic knives but their crook knives are very poor and the grind on them needs to be fettled quite a bit to make them halfway decent.
Any of the other makes mentioned so far are well worth investing in and remember the old adage... buying quality tool first time saves money in the long run![]()
I agree with Mesquite here.
The OP needs ideas for his own Birthday present.
Are there not some really top flight blade smiths here who might have a crooked knife for sale?
