Ratcheting Line wrench

[ERASER5]

I find my self in need of metric line wrenches. I have Mac SAE wrenches for the standard small sizes and a couple of old who knows bigger line wrenches that I have never need to use. I may be in for a surprise.

I have no contacts for Mac or Snap On, so I looked on ToolTopia. I found some GearWrench ratchiting line wrenches. It looks like a spring loaded arm that resets. Any way, has any of you fellows used anything like this? My other GearWrench tool are awesome, so maybe these would be too?

Rusty brake lines are a tough customer and it takes a tough wrench do the job.
