Quiver foam question

[graybarkhunter]

I got a thunderhorn quiver with a fairly new Insert foam in it and I sink my broadheads to the inserts so no blade will be showing,for  safety reasons and all etc. I touch up my broadheads  once a week or so to keep them sharp. I know sinking them into the foam , in and out, exposure to moisture , air and the elements gradually dulls them. I've heard the Chapstick / Vaseline trick to prolong the edge but my question is Has anybody ever cut out the foam and left just enough in the bottom so the Point of the head is the only part touching the foam and the actual blades are not touching anything ( kinda like a kwickee quiver)? Wouldn't this prolong my edges since its not constantly in contact with black foam as if I had sunk them in the foam?? Or am I overthinking the situation.. Hope this is clear, as I'm not a very good explainer! Appreciate it,  Seth

 I think that you can see in this picture the dynamics that a bow and all that's attached to it go through when shot. I got really lucky with my new trail cam set up in the back yard but you search on You tube and see slow motion videos of the action. Maybe this will be a clue why more foam in the hood would be welcome. Wear and tear on the full thickness of hood foam will eventually allow arrows to become a bit loose in the quiver.
 Just my thinking, Ralph.

maybe a little overthought, a sharp edge will dull just sitting in open air if it sits there long enough.

they get dull from oxidation and rubbing against other items...  i put a very thin coat of pitch blend over mine and use broadhead sheaths when in quiver.  I can go a week or more without resharpening easily...then a touch up is all that is required at most.
