Many people ask why some axes are so expensive while others are so cheap. What makes a good axe? What is the measure of it? Today, from the perspective of forging, Xiaobian introduces the inspection methods and inspection standards of the axe, so that you have a simple understanding.
I. Modeling inspection:
① The vertical center line and through the center line of the axe are the axes of symmetry.
② The center line through the eye of the axe and the axe blade fall in the same plane in a straight line, the axe body is not skewed, the axe blade is not skewed (the blade line of the woodworking axe with a skewed edge does not coincide, it should also be completely parallel).
The eye of the axe on both sides of the body symmetry, no deviation. (Ensure that the axe handle is installed on the chopping direction is accurate, uniform force.)
(4) The taper of the horn in the eye of the axe is suitable for both inverted handle and formal handle. Single flare or double flare.
⑤ Thick and thin arc surface transition is not stiff.
⑥ Thickness and cutting edge in line with the design of the axe. Is it split or cutting, axe cheek thickness is appropriate, axe body wedge Angle is appropriate, blade arc is appropriate.
The surface is basically flat, no uneven. No cracks and other defects (reasonable forging temperature control).
Two, material inspection
Forging is mainly based on carbon steel, because stainless steel forging temperature zone is narrow, easy to forge waste. And carbon steel still has great advantages in strength toughness retention. Ax material is mostly tool steel, relatively mature. Heat treatment is mostly local heat treatment, not complicated. The performance is also basically stable. The hardness should not exceed 58. Mostly around 56, the main guarantee of strength.
Steel has little effect on the price (except for some bespoke ones made from Damascus steel).
The handle material has the advanced hickory wood, the cheap has the manchuria, to the hard and strong toughness of the wood is appropriate. Do stabilization treatment (oil) to prevent moisture from entering the wood handle and swelling the wood fiber can not recover. (Also daily maintenance). Wood grain can be seen at the end of the handle, with wood grain vertical ground is better, into a small Angle is good. Anything above 45 degrees is average or below.
Three, packaging inspection
Instruction manual, color drawing, quality assurance documents complete.
The overall appearance is new and bright, no signs of use, the axe blade is sharp, the axe handle is new.
The direction of the handle grain should be consistent with the direction of the back of the axe towards the axe blade.
