Stonfo 446 Type 1 Bobbin Threader
A bobbin threader with a hexagonal soft-touch handle that stays put between spool changes.

Description
Use the 446 when you want to reload a bobbin without fighting a loose thread end at the opening. Put the working end through the tube, catch the thread and bring it back through. Its shaped grip also gives you something easy to find among loose material.

Fit and buying advice
The hexagonal section helps keep it from rolling off the bench. If fit in a particularly small tube is your first concern, compare the Elite Size 1, which Stonfo explicitly specifies for small tubes.
Questions about this tool
Is this the Elite Size 1?
Stonfo identifies this tool as item 446. The Elite threader is a separate 639 family.
When is the shaped grip useful?
It is helpful when you put the tool down between thread changes. Rest the flat section on the bench.
Can I choose it by the spool diameter?
Choose by fit through the tube. The spool dimensions do not tell you the size of that passage.
