Guarantee
We dedicate our blades to the professional end user. Steel selection, heat treatment and geometry were all chosen for the intended task and use. Some rely on our blades with their life; therefore, we stand behind our products and we give lifetime warranty for any material and manufacturing defects of our blades.
Negligence and purposeful destructive abuse will void warranty.
Wear and tear from regular use as well as wear of the Cerakote coating is not under warranty.
I hope that our blades will bring you as much joy as it gives me during our journey.

What the ratings mean
Toughness
How well the edge and blade resist chipping and breaking under impact, twisting and batoning.
Edge retention
How long the edge keeps cutting before it needs sharpening.
Corrosion resistance
How well the blade resists rust from sweat, blood, humidity and salt water.
Ease of sharpening
How quickly you can bring the edge back on ordinary stones in the field.
Toughness, edge retention and corrosion resistance figures are sourced from metallurgist Larrin Thomas's independently tested ratings at Knife Steel Nerds — "Knife Steels Rated by a Metallurgist" (unnotched Charpy toughness, CATRA edge retention, salt-spray corrosion testing). Ease of sharpening is GZ Custom Blades' own field estimate and isn't part of that dataset.
All steels side by side
Toughness, edge retention and corrosion resistance run 0–10 and are Larrin Thomas's published, independently tested ratings (see source above), not GZ Custom Blades' own numbers. Ease of sharpening is GZ Custom Blades' own field estimate. * CPM MagnaMax, A8 Mod and Titanium Gr5 are not covered in Larrin's published ratings — their toughness/edge/corrosion figures are GZ Custom Blades' own estimates instead. Every steel is a trade-off: gaining in one column costs in another. Edge geometry, heat treatment and how you use the knife matter as much as the steel itself.
