CRB spine finder

I use it for every build! Well made product.

Hank Fleming (Georgetown, TX, US)
NOT for fly rod blanks

A lesson learned. Don't use this tool for fly rod blanks they told me after I broke a section using the tool. I have used it for other blanks with no problem whatsoever. The tool gets 5 stars. The published information under product details on the web site, not so many.

Great Tools

Can't wait to use this awesome tool. On your Mudhole Live show I would like to see a demo on the complete assembly of the RBS PRO G2 Power Wrapper. Example, someone opening a present and puts it all together.

Toby Boucher (Amesbury, MA, US)

So far so good still learning

Kenneth Stabler (Philadelphia, PA, US)
A must have

Makes it easier to find the spline and use to check for deflection and guide spacing
