I've used a lot of tools recently, including crowbars and hammers of various sizes. This is a stupid idea, as stupid as multi-tool pliers or the swiss army knife.

It means that it WILL sell, and the buyers will be the category of hipsters sporting well-trimmed beards, thick rimmed glasses and forester's shirts. The customers will be very happy with their product, as happy as they are with their multi-tool pliars and GPS watches, and since they will never actually use it for anything remotely resembling actual work (as with their other posessions) they will remain happy with it.

So.. Good on you, Cole-Bar. You can be as next-gen as you want, you'll never get picked up on an actual building site. You're too flimsy (and expensive) to use as a crowbar (they are TOOLS and they will be hit and bent in every imaginable angle, with any imaginable tool), and you are.. not a good hammer for anything, not as a light precise hammer, not as a heavy duty one. Congratulations, you're about as useless as your target audience, a match made in heaven.

While I agree this looks dumb, I don't understand your loathing for multi-tool pliers. The most useful tool is the one you have with you, so I'm going to carry as many as I can fit in my pocket at once.

I think the "still going after 7 years" means "still hasn't been released after 7 years". It was supposed to be for sale in 2014 and still hasn't shipped yet (from what I can find in Google). The creators have been stringing along their backers for the better part of a decade. As far as utility, it seems like more of a gimmick than something that would get regular use.

I can't think of a time when I've been working on a project and wished I had a 1/2" drive ratchet, a short pry bar, and a hammer but only had space in the tool bag for one of them.

I don't know anything about the product itself, but based on your description I wish I had something like that in the van when i was in a band and we were going on road trips in a cheap van. Especially if they somehow included a hacksaw.

Is there an opportunity to create a business that kickstarts products/services and assures that the funders get the product they contribute to. The business would provide a framework of services to help kickstart the products listed, as well as help with any/all aspects of the delivery (incubation, local resources, grants, testing, etc)

> Do you definitely want to transfer kinetic energy more than momentum? Seems that way; if you're using a hammer, the goal is for all parts of the system to come to a stop. You're trying to deform the material you're hammering the nail into; isn't that measured in energy transfer?

I guess this is tricky because you want all that energy to go into deforming the wood and not the nail. The physics is beyond me here. Intuitively, I feel like weighty hits tend to drive the nail into the wood, whereas fast hits just bash the nail about. That might be more about accuracy though? (Also my anecdote confirmed by someone with practical experience, see other comment.)

Yes, if you're using your arm, there's a tradeoff between speed and accuracy. If you're using a nail gun, not so much.

I was just saying that it looks to me like measuring what happens in energy seems correct, and measuring in momentum looks like a conceptual mistake.

$300MM isn't even an absurdist number for a AAA game [0]. Cyberpunk 2077 single-player was $121MM and they have multiplayer planned so probably add another $50MM - $60MM on top, if not more. I have no doubt that GTA 6 and Elder Scrolls 7 will both come near or break $300MM. $300MM is an absurd amount, but that's just where the market is headed; big and expansive games. I am not defending CIG necessarily but scoffing…

You're not necessarily wrong but $170M completed and $275M still in alpha are two pretty considerable differences. Given that one extra piece of context, I'm perfectly willing to scoff at that number. I find it interesting that there are currently zero Bethesda games on the list despite their fairly broad scopes, which is... telling, considering the reputation of their games. That said, I have doubts that ES6 will hi…

Hmm. For some reason I had thought Skyrim was Elder Scrolls 6. TIL.

I used to quite like browsing KS in the early 10s. I didn't fund that many projects as I got burned by a couple, and a couple more were pretty underwhelming, but I used to like browsing it to see what innovative ideas people had (often my favourite were too far out of the norm, so never got funded). Nowadays I see ads for Kickstarter and other crowd funding sites popup in my feeds quite a lot. The product is often in…

Those silicon lids are great! My mom had a set long before the existence of KS, validating your belief in this case at least.

How are they stringing them along? The Kickstarter can no longer receive funds. Do scammers typically provide updates for 7+ years after they stopped receiving money?

They still accept purchases for in-game content that hasn't yet come out, and so, still raise funds.

I used to be super into my cooking knives, but after a decade of using everything from rubber handled target chef knives to 300+$ japanese art-work knives, I've learned that it's better to buy a 40 dollar chef knife every 3 years than a 200$ one every... 3 years.

This is meandering pretty far off topic but... Why do you need a new chef's knife every 3 years? I've had my reasonably-priced Victorinox for probably a decade. With routine sharpening using quality stones (they cost more than the knife), I don't see needing to replace it in the next decade.

Yeah, If it gets babied and my wife never touched it. The reality is the tip is likely to get chipped, she'll forget it's the nice one and toss it in the dishwasher, etc., and it'll wear out.

I was writing a comment asking what's the point of a lighter hammer, then I realized that a lighter hammer you can swing faster is actually exponentially more effective than a heavier hammer. KE = 1/2mv^2 babe! Physics, bi*ch! :)

Do you definitely want to transfer kinetic energy more than momentum? I reckon a lighter hammer swung faster is more likely to end up with a bent nail. Also, exponential would be 2^v. v^2 is quadratic. (And you need to sub in the F=ma part as well to demonstrate your point, so your gain from the lighter hammer should be less than quadratic. Exercise left to the reader.)

It's probably too late for anyone to see this, but I think momentum is what matters for a hammer. Here is my argument.

I'm assuming that when you swing a hammer, your arm applies a constant force to the hammer. Let's say that force is F, and we are swinging the hammer a distance of d, and the mass of the hammer is M.

Then the acceleration is a = F/M. The distance traveled in time t is 1/2 a t^2 = 1/2 F/M t^2. We want that to be d.

That happens at time t = sqrt(2dM/F). The velocity at time t is a t, so the velocity when the hammer hits the nail is v = sqrt(2dF/M).

That gives a momentum of M v = sqrt(2dFM).

The kinetic energy is 1/2 M v^2 = 1/2 M 2dF/M = d F.

Note that the momentum at distance d depends on the mass. It goes up as the square root of mass. Kinetic energy at distance d, on the other hand, does not depend on mass.

When I've hit hammers with nails, the heavy hammers have always seemed to drive the nail deeper per hit than the light hammers, which suggests that hammer mass does matter, suggesting that it is not kinetic energy that determines how deep the nail is driven.
