Graphite products can be made of bamboo and wood, or copper and iron. If it is made of copper and steel, special tools need to be obtained to make dual-purpose bamboo tools and dual-purpose iron tools, and the surface manufacturing process is limited.

Looking for a larger brass hand stove?

It seems that everything made of metal must be welded for heat conduction or welding.

Wood is okay, but the metal of the handle is made of titanium alloy, but it is not directly welded on. The raw material of the handle can be stamped into a thermoplastic elastomer by stamping on-site and then welded on. But it hurts when welding

Metal can be made into dual-purpose tools. The material is too complex

t_t Make a transparent shell, put a piece of iron inside, and it can be used for dual purposes.

Copper can be directly melted and cast into dual-purpose (｡･ω･｡)

can not do this

The weight of brass is 1g. When two pieces are put together, the thickness is 50mm. It is lighter by one square, and 4g of wood can’t do it.

Metal can be used for dual purposes, but the internal parts of the handle must be different. One aluminum alloy handle can weld the internal parts of two wooden handles. One iron handle can weld the internal parts of four wooden handles,, I still ask for help @吧!  :)

My first reaction when I saw the picture of the subject is hot-dip plating.

Iron and iron can be welded into a dual-purpose tool, metals cannot

The weight of the aluminum alloy handle is lighter than that of copper or aluminum, but the welding price is also relatively low. Metal handles are not easy to make, either you have to have good craftsmanship to achieve light but durable, or the price of metal may be relatively high. If they are all finished products or picked up from a certain treasure, the cost and price of the two materials are similar. If the handle is to be used in a toolbox or the like, I think there will not be only one direction, so the goal of low cost and durability will be variable.
