Jackhammer is a three blade mechanical head. The blades are held closed
by an O ring. Their accuracy is excellent, grouping right with my field
points. The Jackhammers have a fairly wide cutting diameter 1 ¾”, and
the blades are reasonably sharp out of the pack. My only complaint would
be that they are slower to open than many other mechanical heads I have
tested. I would say they open just a bit faster than the Spitfires made
by new archery products. They are also fairly strong, and the blades
have little cutouts that allow you to tie them shut for practice.
In the Orange test the Jackhammer only partially opened by the time it
exited the far side. In the plywood it did not fully penetrate, but did
get most of the way through without any damage. In the steel drum the
head penetrated the first wall, and bounced off the far side. One blade
had the tip bent, but it was minor, and no cutting ability was lost.
Overall I liked the jackhammers, but they are slower to open than most
other heads. They however are strong and sharp. The cutouts in the
blades make practicing with them a snap by simply tying the blades shut
with dental floss or serving thread. If you are looking for a strong
head with a larger cutting diameter the Jackhammers would be a good one
to take a look at.
Please note as
more test information becomes available, it will be updated and posted.
Make sure you check back periodically to see if the head you're
curious about shows up on the measuring tape. If you’re interested in
donating a head for testing, email
email@example.com or visit Huntingforums.com,
Bows and Arrows forum and see 5shot. Thank you and enjoy.
