The size I have are 10,12 and you're right they are less than sharp. I like the shape of them and I'm having quite a time finding another hook that has the same shape(or close) and size I want without bending it, I know you can bend some hooks I just worry about doing that and if I can manage it I'd rather not. So, since we're here some advice on sharpening hooks correctly would be nice. I can't find the 37160's local so far but can get them on the ever lovin internet. Any one that has a fly shop and has them I'd like to hear from ya... Lookin for size six. Thanks.
