Powerstrike hammers

Just wondering if anyone here has experience with these hammers.

Their website is www.powerstrikehammer.com.

I am intrigued by the design of them. They are also made in the USA.

The price is steep though, 150 bucks per hammer. All the reviews I have read have been positive. Trying to decide if they are worth the cost.

They sure do look pretty though.

would that spring test have (possibly) different results if done at 90 degrees and upright positions? both more common striking angles for framers.

...not a physics guy...would the overall weight and it's distribution change the amount of "work" each hammer does when changing the angle? (inertia ?)

I can't really wrap my mind around all the applied physics of the design either.

All the written and video reviews say the performance is hard to describe but they are all positive. Pretty much if you try it you will like.

I also can't get around the price tag.

Pretty sure this is how it works in a nutshell:

1) Hammer swung.

2) Face contacts nail, spring inside face (helical/coil) compresses at point of impact.

3) Swing stops depending on how fast hammer was swung. Force exerted on nailhead can be calculated, as long as spring constant is below this amount, the spring is allowed to compress and at the end of the swing, (reaction force) expand driving the face into the nailhead again.

Like a pseudo deadblow, except with a spring damping/absorbing the vibrations, and then provided your arm is still holding the hammer to the nail at the point of contact, the spring delivers some extra oomph when it expands. A deadblow just has shot that dampens the vibrations.

Worth the $150? If people are willing to pay upwards of $200 for a Stiletto titanium hammer, sure. Would I buy it? No, because I don't really worry about the extra steps they took to finish it, such as the conical ball-end hammer face - If I need nails sunk below the surface, I'll use a nail set/punch. I have no problems driving my nails flush - if you're using a hammer, it's going to mar the surface of the material regardless. Not to mention, most of the time I'd use a nail gun.
