Found this item at a garage sale: an antique Dutton-Lainson barbed wire stretcher. The company is still in business and these can be found in some hardware stores under the Goldenrod brand, usually for less than $75. We’ve done a basic test on our KRISTI tracks and it seems to work well. This might be a carry-onboard item once it gets some basic service. And helpful to repair those Forest Service range fences after, you know, access issues.
