spear material confuse

  • I have read few posts and there is a 3 type of shaft

    • the one i use from RA is quench spring steel
    • second cressi stainless steel but don't know if harden or not its cobber color
    • third the stainless from pathos and teak sea which is white color
    • their is a hardened alloy 17-4 ph stainless also



    anyone can help to distinguish between these ,I want to have a spear won't rusted like RA and also have same hardness and density to not overpowered .

    youre not gonna get anything harder than carbon steel. RA,Freedivers, Aimrite, wong, mako, and torelli all use similar "south african" carbon steel, Cheep, and effective, but it does rust quite easily. Ive found that RA shafts have the best corrosion resistance, most of the others rust completely within a few months.


    anywho, Mori shafts are hard, and really well made, but they are so hard that they tend to chip when sharpening with a grinder


    17-4 are good if diving coral reef, not the best around rocks but not bad. I think neptonics, hammerhead, speardiver, and a bunch of other shaft manufacturers and spearfishing brands carry 17-4 its cheap and readily available.


    cressi and other traditional european pipeguns tend to have very narrow 6-6.5mm shafts of either stainelss spring steel. They arent usually hardened too much, so watch out for rocks and coral, from my experience in Hawaii they tend to be a bit overpriced for what they are (OMER) but thats probably just importing.


    Ive used pathos, and bleutec shafts both I think are only hardened at tip and notch. they work well, but are pricey.


    bottom line, all materials have their positives and negatives, find the ones best suited to the type of diving youre gonna do.


    Goodluck,

  • If you can get Italian shafts, buy Devoto sub. Best European ss steel. Then.you will have the flopper and pin problem. In Europe they are too weak.


    But again, nothing is harder than CS. A SS shaft will bend before a CS shaft rusts. At least when I use them.

  • I need to balance my gun and choose the accurate set up ,bad experience with salvimar 160 cm shaft SS it whip very easily ,I am afraid to order more SS and all my wood gun will be ruin ,pathos available in cheap price .
