Here's a rare example of a superior tool design that costs less than an inferior design.First off, we'll start with the lesser design. Japanese tool brand Suizan makes this Folding Ryoba (double-sided) pull saw. The handle folds for transport but, once folded, they only protect the teeth on one side. In order to protect both sets of teeth, you need an additional sheath or case. It retails for around $50. ToughBuilt, a U.S. tool brand that seemingly came out of nowhere a decade ago and has exploded across the marketplace, offers this Folding Pull Saw. Like Suizan's offering, it has both rip and crosscut teeth; unlike Suizan's the handle folds to protect both sets of teeth, like a gigantic butterfly knife. And the folding handles are actually made with steel, unlike Suizan's, which are polypropylene. Here's the kicker: The ToughBuilt saw retails for $30. How are they able to offer more tool for less money? My guess is that they manufacture in China; until recently the saw was sold for as little as $18, and the price bump is probably in reaction to the tariff war. Depending on how things go, this tool might eventually end up costing more than Suizan's.
