A bit sensitive, eh?
After doing a bit of searching on the Internet, I have discovered that there are more than few people who never got the memo 100 years ago that you don't need a
toothpick, a
carabiner, or your
thumb to tie a blood knot.
So now I know where you find the confused people to show your hack to...
Based on THOSE videos, anything would be an improvement, err excuse me, a hack. However, trust me it's nothing new.
Here's MY "hack" to your hack (although I'm sure I didn't invent it):
When you do the first series of wraps and put the 1st tag where the two pieces cross, instead of trying to pinch the 1st tag between your fingers or let it do what it wants, fold it back across the wraps you just made and hold it and the wraps between whatever fingers work best. That will keep you from losing the 1st tag or having it pull/fall out of the opening as you make the next set of wraps.
After you have made the opposite 2nd set of wraps, if you find the opening is a bit small, with the 1st tag still folded over, slip it between the fingers of your other hand and just pull back on the 1st tag and it will enlarge the "opening" making it MUCH easier to put the 2nd tag through. That pays huge dividends if you are using fine tippets when you are trying to "thread" the needle with the 2nd tag.
Another hack to that hack:
If you are adding tippet to an existing intermediate section and want to keep that intermediate section as long as possible, make the first series of wraps with the material you are adding because if you are incorporating the 1st hack, you will want to fold that tag over before winding the second set.
The 2nd set of wraps with the intermediate section doesn't need to have as long a working length because you don't need to fold the tag over on the 2nd set of wraps so you can save an inch of leader.
A final hack to the hack of the hack:
I find blood knots are a WHOLE lot easier to tie if the material is under tension. Therefore, whether fishing or tying knots at home, I don't cut the material I am adding off of the spool until I FINISH the knot and I try and have it pulled taught somehow (with a tippet dispenser or in a pocket) when I tie the knot.
I've watched more than few fishermen struggle to tie a blood knot because they cut a piece of tippet they planned to add off of the spool first.
When fishing, I also let a belly of line drag in the water and hold just my leader to get some tension on the end where I am adding the tippet.
