    I am looking for a two part epoxy to bond a spear head to a wooden shaft. I hope there is a knife maker that can advise me on what they use on knife handles. Thanks

    Back when I was making knives I used Devcon 30 minute epoxy. I was just a hobby maker and never sold a knife. I gave them to various friends and family members and also kept quite a few. The epoxy has never failed on any of them. I do make sure to build in mechanical locks in everything in the assembly so the bond isn't strictly dependent on the epoxy's grip. Roughing up the glued surfaces is also beneficial.

    Not a knife maker, but have glued a number of maul and axe heads to handles. Whatever comes in the axe head epoxy kits works and has a measure of ductility that the epoxy does not chip.

    This is clearly overpriced

    Flexpoxy used to be in marine stores, what I used was remarkable for impact type applications.

    I have used this two part Evercoat epoxy

    why I used it, is because it flows like honey. It is messy in application, so wipe Johnson paste wax on the things you don't want glued, but because it flows, it gets into little spaces.

    Haven't ever tried to glue a spearhead up (or any knife handles) but I have done a fair amount of epoxying stuff that endure high stress in the marine world (mostly saltwater) where any gluing problems quickly become apparent... What I'd look for is a slow curing (two hour cure) epoxy glue (not resin...). If you're wanting high quality bonds in small amounts JB Weld makes a very good product... I buy my epoxy mostly by the pint or quart kits - by Fasco...

    Many of the commonly available 2 part epoxies from the home stores will be sufficient. The prep is a key part so that the materials will bond well. Clean, oil free surfaces, sufficient roughness so that the epoxy can adhere and bond to. Don't over squeeze/clamp the items as this may squeeze out leaving a starved surface area.

    I've used Marine Tex in several different applications on my skiff with very good results. It comes in both white and an iron gray with all the info needed to use it properly (and in smaller amounts than the Fasco I recommended. The advice given by RA40 is right on the money about the prep and use..

    Marine Tex or Deacon epoxy both work very well. Please follow the advice given above about prep, a clean and prepped surface makes the job much more durable.

    Marine Tex is magical, I seem to remember it will even set under water.

    I used the gray version to repair a gash in my auto fuel tank when nothing else would work. The white matched gelcoat pretty well and worked great.
