While its certainly a fun book to look at I feel like it has two major flaws; it doesn't explain the differences between weapons or how they evolve besides the basics like "longer and shorter blades are used differently" and "cutting and thrusting weapons have specific designs." There's no exploring the physics, mechanics or evolutionary demands that made some weapons relevant and some obsolete. There are also some cultural blind spots that prepare this work; I can understand limiting the number of modern firearms since many serve similar functions and may look very similar, but some cultures have very little representation. Aside from stand alone missing weapons (Egyptian Kopesh, Afghan Jezzail, Falchion, etc.) there are entire cultures that are either glossed over or underrepresented. South East Asia is solely shown through Indian arms, missing the diverse weapons of the Phillipines, Indonesia, Thailand, etc., while China seems to only have a few examples of swords and maces. Also, Eastern Europe gets almost no mention before Napoleon; skipping the Hussars and Cossacks make it look like sabers just magically appeared in Europe.
