FIELD: weapons and ammunition.
SUBSTANCE: invention relates to sports arms field and can be used during production of fencing weapons blades, in particular backswords, sabres and court swords blades, to increase blade handle and welded seam strength properties while saving used expensive steel and increasing blade rigidity. Two large diameter bar workpieces 1 from carbon steel and smaller diameter polished bar workpiece 2 from martensite-ageing steel are connected by contact butt welding. Then, performing reduction of semi-finished product by cold rolling to form first double stepped workpiece, and then blade required profile: for rapier is rectangular, for sabre is trapezoidal and for court sword is V-shaped.
EFFECT: after deformation performing machining with subsequent thermal treatment, carried out in two stages, first hardening only blade section from carbon steel, then, performing tempering of whole blade, wherein performing simultaneous tempering for blade section from martensite-ageing steel and for blade section from carbon steel.
