Here's a comparison of 4 Heavy Duty 8" Needle Nose Pliers:
Snap On 196CF ($51)
Doyle 8" from HF ($10)
Klein Journeyman J2038N ($35)
Channelock 318CB ($25)
(Note: Knipex is excluded because all I have is their light duty 26-200 model)
I'm breaking this down into:
- Jaw dimensions (min. tip width, thickness, width at hinge and usable length)
- Description of jaw closure geometry
- Serration pattern
- **** hair test. (will the pliers hold a .003" **** hair in the jaws - actually a tiny magnet wire)
- Jaw deflection test. (grab a piece of steel using 1/2" of jaw and attempt to twist the metal and observe any jaw deflection.)
Snap On:
- Width at very tip - .10"
- Jaw Length - 2.3"
- Jaw Thickness at hinge - .43"
- Jaw Width at hinge - .75"
- Jaw geometry - Tapered jaws, tips close then with a little pressure cutters close
- Serration Pattern - Diamond - fine serration
- **** hair test - Pass
- Jaw deflection test - Jaws deflect some
Doyle:
- Width at very tip - .19"
- Jaw Length - 2.3"
- Jaw Thickness at hinge - .52"
- Jaw Width at hinge - .93"
- Jaw geometry - Tapered jaws, tips close simultaneous with cutter
- Serration Pattern - Diamond - fine serration
- **** hair test - Pass
- Jaw deflection test - Jaws deflect some
Channellock:
- Width at very tip - .14"
- Jaw Length - 2.4"
- Jaw Width at hinge- .93"
- Jaw Thickness at hinge - .51"
- Jaw geometry - Tapered jaws, tips close simultaneous with cutters
- Serration Pattern - Diamond - course serration
- **** hair test - Fail
- Jaw deflection test - Jaws deflect some
Klein:
- Width at very tip - .19"
- Jaw Length - 2.3"
- Jaw Thickness at hinge - .49"
- Jaw Width at hinge - .92"
- Jaw geometry - Parallel jaws close simultaneous with cutters
- Serration Pattern - Opposing diagonal
- **** hair test - Pass
- Jaw deflection test - No jaw deflection
