I've been using these knives for thirty years in my sign shop and thought I knew everything. The breakdown of steel grades and how they actually relate to edge retention was worth the price alone; it explained why some blades last twice as long. The chapter on business opportunities even sparked an idea for a niche reselling service. It's a touch dense in the middle chapters for my taste, but I appreciate the thoroughness.

It's a solid, informative reference, and I can't fault the detail on maintenance and troubleshooting. My main reservation is that it feels a bit academic in places; the jargon gets thick even with the glossary right there in the back. I was hoping for more practical recommendations on specific brands for different budgets, but it stays pretty neutral. I learned a lot, but it's a reference to consult, not necessarily a book you read cover-to-cover.

Finally, a book that treats this subject with the seriousness it deserves. As a professional model maker, I need precision and reliability, and the chapter on choosing the right blade based on cutting frequency and cost-per-cut has legitimately changed how I stock my workbench. The clear, no-nonsense explanations of blade geometry clarified a lot of the guesswork I was doing. I've already bought a copy for my two junior staff members.

This is a very practical handbook that covers everything from types to business models. The chapter on installation and usage is excellent for training new employees, and I found the comparison of different supplier tiers in the business chapter quite useful. I'm rating it four stars because the future trends chapter felt a little speculative and light on concrete detail, which is a bit of a letdown after the rest of the book's grounded approach.
