Jack Richeson Canvas Pliers (line)

Not for: Artists who use only pre-stretched canvases or rigid painting panels.

Claude also lists Jack Richeson among the brands that matter.

Fredrix (brand)

Wide-jaw pliers grip canvas evenly so you can pull consistent tension while stapling.

Not for: Anyone stretching only very small canvases who can tension the fabric by hand.

Staple length. Staples around 1/4 to 3/8 inch suit most stretcher bars Staples that are too long split thin bars. Staples that are too short pull out under tension.
Plier jaw. Wide, serrated jaws with a hammer heel Wide jaws spread the pull and avoid tearing, and the heel acts as a lever against the bar.
Stretcher keys. Keys must match the slot style of your stretcher bars Keys let you retension canvas that slackens over time.
