What it is
The Hareline Stonfo C-Clamp is a vise-mounting clamp base that attaches your tying vise to the edge of a bench or table. It’s built from aluminum with stainless steel parts, and it stays rigid and stable under pressure with low vibration and no wobble. The footprint is compact, so it doesn’t eat up your tying space.
What to tie with it
This isn’t a tying material for the fly; it’s what holds your vise steady while you tie everything from small dries to larger streamers. Use it when you want a solid platform for consistent thread control, firm hair spinning, and tight wraps without the base shifting. It also makes sense for a travel tying setup or any small workspace where you can clamp to a table.
Flies and the fish they're for
Because it’s a mounting base, it doesn’t show up in specific patterns, but it supports the tying that leads to them. A steady, low-vibration clamp helps when you’re stacking and tightening hair for deer-hair bass bugs for largemouth and smallmouth in ponds and rivers, or when you’re cinching down bucktail and dumbbell eyes for Clouser Minnows for smallmouth, stripers, and redfish in rivers, bays, and the surf. It’s also handy for small trout flies on light wire hooks, where any wobble makes fine thread work harder.
How it compares
Compared with a pedestal base, a C-clamp is less heavy but can deliver maximum stability when you have a solid bench or table edge to clamp onto.
