A long time ago, almost a decade ago, I reviewed hand tools and evaluated prototypes. Since then I've done it very rarely, but this hammer is an example of excellent functional design and even decent aesthetics. I am committed to encouraging others to study this tool to become familiar with what great tool design is. It's not perfect - the Japanese-style handle, technically flattened, octagonal, is too square for a comfortable and secure grip (although the straight-grain wood is knobbed and the strap makes it easier to grip). his weakness. But it also determines the optimal function in relation to the intended use in every other area. I could go on for several pages, but instead I invite you to muster your own critical eye.
