Hi guys, Josh Bowmar here from Bowmar Archery. 

Today, we are going to dive into a massive mistake that most archers make. A lot of you guys are probably doing it and don’t even realize it and that is knock pinch or knock tuning. We are going to dive into how to check for it and how to fix it if you do have it.

What is knock pinch and does it make a difference? YES! You could have the most perfectly tuned bow, the straightest arrow, perfect release, and still miss if your knock isn’t perfect. In my Bowmar Bowhunting YouTube video, I show you how to check for this. 

Step 1:

The first thing you are going to do is take the knock off your arrow. Take the knock and put it in the d-loop by itself. Now, pull your bow into full draw. Pay attention to the direction of the knock. My knock was pointing up, inducing knock torque, which causes all sorts of issues. The goal is to have the knock sit flat. To fix this, you will want to make sure your d-loop is tied correctly.

Step 2:

Next, I put my bow into the bow press – a bow press is not necessary, but it does make the process easier. Before I tie on the d-loop, I tie on serving. There’s actually a way to tie the serving where it will force the knock to be perfectly parallel. When the string angle comes down, and you don’t use serving below, the knock will naturally point up, which causes a lot of inconsistencies on the rest itself. I like to use .021 serving. You want to be sure to use the bigger serving on the bottom of the knock! I show this whole process in my video. The serving above the knock is not necessary, but I like to do it in case my d-loop wears and I need to replace it. In that case, I am able to take my old d-loop off, replace it with a new one, and everything is sited  because the serving stays. 

Step 3: 

The next step is to tie on the d-loop. You want to make sure your d-loop is tied on correctly. I have another Bowmar Bowhunting video that shows how to correctly tie in a d-loop. I go into great detail about the importance of correctly tying in your d-loop. 

Step 4: 

Take the bow out of the press (if you have one), draw back your bow, and see where your knock is pointing. 

Hitting a bullseye is already really hard. You don’t want to let something as silly as a knock be the reason that you miss your big buck. This tip can save you on forgiveness! I hope  this tip helps and that you go check all of your knocks.
