The A.B. Biller LTD is handcrafted from selected teak wood; its trigger mechanism and safety are fitted directly into the gun barrel. It is extremely difficult to obtain large quantities of truly straight barrels in these precious woods; therefore, this speargun is a limited edition. The A.B Biller LTD is available in 4 sizes. Teak is one of the most valuable kinds of wood, but its use is limited by scarcity and high cost. Due to the heavy silicate content, it does not cause corrosion when placed next to metal; hence, it is extremely useful in ship building. No satisfactory substitute has ever been found for teak in this line of work. The A.B. Biller Teak speargun is as beautiful as it is functional. The barrel and butt piece are carefully cut from the same piece of wood so the grain matches precisely. The wood is hand-rubbed with boiled linseed oil.
