The Sharpest Blades

The damp atmosphere of the marsh has taken a toll on my metal tools. It's made woodworking a lot more difficult than it ought to be, so I've given up on metal blades.$B$BIt turns out that the marshfang slicers living to the south and west of town grow blades that are sharper than any steel I've ever owned. They're also resistant to rust and wear. It's just a little tricky to attach them to a handle, but I think I've got it figured out. I'd appreciate any blades you could bring me.
