Knife Engineering: Steel, Heat Treating, and Geometry - In-Depth

Our review of Knife Engineering: Steel, Heat Treating, and Geometry finds it to be an indispensable reference for anyone serious about knife performance. Written by a PhD metallurgist, the book is not a step-by-step knifemaking manual but an authoritative exploration of how different steels, heat treatments, and edge geometries affect toughness, edge retention, and corrosion resistance. Readers looking to understand material tradeoffs, compare popular steels, or choose a heat treatment will find direct, evidence-based answers and useful micrographs rather than anecdotal guidance.

Key Features

• Comprehensive metallurgy: Explains the metallurgical reasons that steels perform differently, giving readers a deeper grasp of why one alloy outperforms another in a given role.
• Steel performance ratings: Provides clear ratings for toughness, edge retention, and corrosion resistance across popular knife steels so comparisons are fast and practical.
• Specific heat treatments: Recommends heat treatment parameters for individual steels, helping makers and enthusiasts replicate tested conditions.
• Micrograph evidence: Includes micrographs of over 50 steels so conclusions are supported by visual metallurgical data rather than just opinion.
• Geometry insights: Discusses how edge thickness and grind geometry influence wear and fracture behavior, answering common performance questions.

Who It's For

This book is ideal for knife enthusiasts, independent knifemakers, and bladesmiths who want to move beyond folklore and understand the scientific basis for material and heat-treatment choices. It is particularly useful for makers who already have basic workshop skills but need reliable, technical guidance on steel selection and treatment.

Readers seeking a beginner's how-to guide for step-by-step blade construction, or those looking for project plans and tooling instructions, should look elsewhere; this text focuses on metallurgy and performance rather than assembly instructions.

Pros & Cons

Pros

• Authoritative explanations from a metallurgist make complex topics accessible and credible.
• Practical steel ratings and recommended heat treatments shorten the learning curve for makers.
• Extensive micrographs and data tie conclusions to observable structure rather than anecdotes.

Cons

• Not a hands-on knifemaking manual, so readers expecting shop-level step-by-step guidance may be disappointed.
