Some tools are made with the expectation that the user will sharpen
and hone them before use, but most people don't!

Well actually most tools can be sharper than with the original edge that
the come with. Its all relative. Take 95% of carbide tooth blades,
chisels, hand plane knives to name a few. Typically the resharpened blades
always come back sharper than when the tool was brand new.
