Package Content
BOX
All knife we ship shall include a laser cut wooden box, which is designed to protect the product. Some time the production and resourcing may lag behind our sales, and we may send the package in an alternative packaging, but we always advise you on that.
SHEATH
All of our blades will arrive with a custom fitted kydex sheath.
STATIC CORD
I want to provide you solutions, and not problems. Therefor I deliver each and every knife ready to use right out of the box. For all smaller and EDC sized blades where it is practical, we attach a static cord from '550 paracord to the sheath. This can be used as a tether to go around a belt or beltloop, and you can tuck the blade into your pants right out of the box. How practical is that? Japanese Samurais were wearing Katanas in a similar fashion for centuries, and this is how i carry ALWAYS, 365 days at least one of my carry blades. Try it out, you will like it. If you have any question, do not hesitate, i help you out with that.
CERTIFICATE
All blades we ship will come with a Certificate of Authenticity. The production blades will come with an A4 size Certificate folded, English Hungarian with basic instructions and Knife Care.
Custom knives have a serialized, dated custom certificate. I beg your pardon for my handwriting in advance.

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.
