If you shoot the same dart, or use a given degree angle for the tips... and sharpen them all in the same way...

Actually past a certian point, sharpness doesn't matter.

I cannot tell the difference between a razor blade and an xacto cut. Both are friggin sharp, but the razor(expecially one of the old gillette blued)is bloody sharp while the razor is just razor sharp ;) they both cut about the same.

Realistically, if its sharp enough that it goes right through the skin, and you can't tell....

go for it.

I love the idea, but I lack a phonebook.

Teach, I respect you a great deal, but in my experiance with different levels of sharpness of various knives, broadheads, spears, and blowgun darts...

two points with the SAME edge angle, both sharp enough to shave off fingernail shavings, even if one is far sharper than the other, will penetrate virtually the same.

AKA one might be sharp enough to shave with easily, one might be barely sharp enough to shave fingernails. There is a vast difference in sharpness, but both are pretty sharp.

They penetrate about the same.

I have found with a spear, it will sometimes go deeper when you don't make it super-crazy-dangerously-friggen sharp, but just use a 200 grit whetstone. It will be slightly serrated.

Seriously.

Sharpen two points to 35 degrees, 3 edges. make them sharp enough to shave little pieces off your fingernail(an 200-400-800-1200 grit works well). then dull one so it will just barely cut into the fingernail, and shoot both with the same power. They will penetrate virtually the same, the sharp one might go a couple pages deeper.

35 deg is pretty dang sharp for a point.

27 is better, but much more fragile.

Oh.

Now that you have clarified that you are talking about ROUND point, with a sharp tip, like a needle, this all makes sense.

I was talking about these sort of points, which is what I have always used-

Therin lies our problem.

I file that sort of points onto my target points because they penetrate much better than rounded points, and last much longer when shooting wood targets before becoming blunt.

They also make a nice little triangle-hole, which is much easier to see when there are a ton of holes in the wood.

I believe you meant the lesser the angle, the more penetration... a 25 deg point will go much deeper than a 70 deg point....

measuring from the axis of the wire...(aka angle from the lengthwise axis of the dart... I don't think I am being very clear here).

Yep, a ballistic pendulum is signifigantly more accurate than a cheap chrony... but it is MUCH harder to use.

But I am a cheapie...

lol

i do love ballistic pendulums.

BTW you can simply attach a section of pen ink to the pendulum and it swings... and marks where it swings...

Never try to use a ballistic pendulum for a potato cannon.

It requires a heavy-arse pendulum.
