Complaints about Steellogy blades are the exception, not the routine — but when one is raised, it goes through a documented internal procedure, not an ad-hoc reply. That is the point of this post: to make the procedure visible, so that if you are evaluating Steellogy as a supplier, you know what the failure-mode response actually looks like, and so that if you are already a customer and need to raise something, you know what to expect. Why a documented procedure matters more

No batch of Steellogy blades leaves the production floor without a dimensional check against the drawing and a hardness measurement on a representative finished part. The inspection happens after heat treatment and final grinding — when the blade is in the form the customer will receive it — and the record stays with the batch. If a batch does not meet spec, it does not get packed. This post explains, in concrete terms, what we check, how we check it, and what ends up in the

The right grade of tool steel for an industrial knife depends on the material being cut, the cutting action, the machine geometry and clearance, and the required run length between sharpenings. Picking the grade is not a preference — it is a calculation, and getting it wrong is the most common reason a replacement blade underperforms the original. The grade selection question, the short version There are three main steel families, plus two common performance additions, that c

Not sourced from a third party and rebranded — produced under our roof, by people who can pick up a finished part, walk it to the engineer who set the geometry, and confirm whether a bevel, radius, hole pattern, or edge finish matches the intended function. This is the difference between a manufacturer and a supplier list, and it changes a long list of things you are allowed to expect from us. Why "in-house" i
