I've heard you can put these in a vice and open the gap up @ 1/4 inch.
I do this as well. I also offset them when I open them up. Not a lot but just a little. Also don't forget to put a hook file to them. About 1 out of 8 have funky tips on them. Some points are real long and skinny and are actually bent over. You have to use pliers and straighten these and resharpen them. I have had a whole box of the 14/0's that all looked pretty good, and I have had a box of 25 hooks and there were a LOT of them that were jacked up. Just pay attention to them before you put them on a hook..
I found a place that has the 16/0 circles for .50 cents a piece and $1.50 for the 20/0's..(

A fella I now that has been catching sharks for a long time told me if you can slip your thumb(the thickest part below the only knuckle on your thumb)between the point and the shank you will have enough of an opening to get the hook into the corner of most sharks mouths and hook them just like a circle is supposed to do. I actually offset my 16/0's a tiny bit and sharpen most of them up as well.
www.leadertec.com also has the 16/0 circles for about .70 cents a pop..Good luck..
Oh I almost forgot .. I saw the Mustad 15/0's at Cabelas in Buda tx and the were about $10 for a box of $25..Thats about .40 cents a piece.. Not bad and they are a tad bigger than the 14/0's..
