When to choose it
Model 5-310 has a four-by-three-and-a-half-inch blade and is designed to flex to 90 degrees during use. Measure the joint and room around its two faces. Compare a smaller wing profile if a nearby return gives less clearance.
The listing describes flexible stainless steel and a rubber grip with a metal end. Choose an adjustable inside tool if the intended angle is wider or narrower than the angle this knife is designed to work.
