Lumbricus makes me proud. Those burrowing holes you see in the briar and ebonite stem are my resident worms at their best. Cobblers have elves, pipe makers have worms, etc. Lovely Italian briar that moves from red to yellow with a delrin tenon that curves oh so elegantly into it's ebonite stem. The Monstrosity "M" is engraved just under the shallow mortise. Here are the stats for Lumbricus:
Inner bowl depth: slightly deeper than 1.25"
Inner bowl span: .75"
Weight: 2.8 ounces
