Sharp blade style spearfishing tips
Many years ago blade type spearfishing spear tips were available that did more than skewer the prey (e.g. the Undersee cast steel bladed (4) “Mako” and (2) “Cutlass”, the Sampson 3 blade triple flopper tip), they created more structural damage on arrival that incapacitated the fish, especially when blasted by guns with significant firepower. These tips have become only a memory for some in a world of tricuts, quads and pencil point tips, but these archery tips look like they could hand out more damage if fitted to a spear. The fish may sustain battle damage which may make photography inadvisable after capture (wrt the image of the sport to the Public at large), but you (and others) get to eat the fish which is the main goal of the hunting exercise.

Re: Sharp blade style spearfishing tips
These tips present some intriguing possibilities for spin stabilized projectiles in underwater flight.

Re: Sharp blade style spearfishing tips
You would need a shaft without any features sticking out like shark fins or flopper etc. otherwise you would be loosing significant energy in overcoming the drag since you are moving water sideways.
Well I guess you would be loosing quite a bit of energy anyway in just having the shaft rotate. For hunting relatively small reef fish in the Mediterranean I certainly prefer the smallest hole possible. I think shot placement is the deciding factor for the mortality of a shot. |

Re: Sharp blade style spearfishing tips
But they do look bad ass. I think Rambo would use them if he ever tried spearfishing.

Dimensions on these seem small.If the OD was more 15 to 20 mm and had a 6mm or 5/16 female end I'd snap up a few just to try.

Re: Sharp blade style spearfishing tips
You got me looking,thanks.These have a bigger radius,all stainless construction but are close to 10 bucks each.
https://www.midwayusa.com/product/85...tter-broadhead I'd need to source an adapter male to female. I pay about 25 bucks delivered for the JBL 845s I normally use freeshafting so it would be less than those.

Re: Sharp blade style spearfishing tips
If you are looking into converting broadheads into speartip application then look at Bass pros version of the g5 montec it's called the blackout toxic fixed blade. Much cheaper. . It's basically the same head without the trocar tip and replaceable blades. It can be sharpened on a flat stone. I use them bow hunting and the are the bees knees. muzzy and Thunderhead is another good choice

Those with long memories will recognize the "Aquacraft/Bandito" Lionel Long handle. http://patcoinc.com/aquaguns/aquaguns.html http://patcoinc.com/aquaguns/gun_accessories.html http://patcoinc.com/aquaguns/bh2.html The smaller blade width cast steel fin tips such as the old "Mako" tip don't suffer bent blades, but to keep their sharp cutting edges need to be made of hard stuff and tend to be brittle on rocks, not unsurprisingly. Fish tend to hang around rocks or open water predators swing in to harvest the lesser life in the food chain that seek out the protection of underwater structure, so there are always tip hazards within shooting range near such structures. Oil Rig legs don't do tips much good either, so one always needs access to replacement ammo. Last edited by popgun pete; 12-29-2018 at 03:33 PM. |

Re: Sharp blade style spearfishing tips
Patco guns... slightly negative to prevent float away... Seems like they are meant for scuba spearfishing, right?

Re: Sharp blade style spearfishing tips
I don't own one, but I do have an old stainless steel "Bandito" with blue plastic parts which is basically the same gun (different muzzle though), but it is a short gun and is no floater. Depends on the thickness of the tubes and if they are sealed, and of course the tube length for the volume. My Biller and Sea Hornet stainless steel tube guns float after the shot, just! As these Patco guns are described as slightly negative they would be OK for scuba use, but don't forget for years spearfishermen used tube guns that don't float such as Swimaster/Voit/JBL models that had flooding barrels. The muzzle looks a bit heavy and the cocking stock probably floods, hence that may tip the balance towards sinking.

Re: Sharp blade style spearfishing tips
As luck would have it here is a "new old stock" Undersee MAKO spear tip! But the seller wants 65 bucks for it!
The flash chrome plating has come off and it needs a touch of an oilstone to sharpen those four blades. Moisture in the air has done for the plating over the many decades of storage. https://www.ebay.com.au/itm/Vintage-...53.m1438.l2649 Last edited by popgun pete; 02-11-2019 at 02:23 PM. |
