Seam Separation Knife

About This Item

The ideal knife for removing tops, backs and fingerboards from most instruments.

The stiff 3-3/4" x 3/4" high-carbon steel blade has a long knife edge that is capable of cleanly entering narrow cracks for separating a glue seam.

The gentle wedge-shaped cross-section exerts the ideal pressure to help the glue yield, yet doesn't tend to cut into the wood. The blade can be heated and moisture applied to help speed the work. Hardwood handle.

A very useful tool.

Multipurpose Knife

By

Verified Buyer


When you need a good, sharp, sturdy blade to wedge in between things, this is your knife. For the price, it is superbly made and useful in many applications.

Cool tool

By

Verified Buyer


I like this tool a lot. It will replace some of the knives and chisels I have used in the past for multiple jobs. Including hand cutting v shaped patches for cracks in spruce tops.

Another Pleasant Surprise

By

Verified Buyer


Just like the offset knife - this is a dandy tool. Inexpensive and well-made in good old Nippon(Japan). Sort of the Ibanez of knives ;-) The blade is great- I use it as-stated to open up seams I'm getting ready to re-glue.

Fretboard removal made easy

By

Verified Buyer


I will never attempt another fretboard removal with anything but this tool. It cut my time by 60% and leaves the separation seams clean enough to not require additional finishing upon reassembly.

Simple Excellence

Verified Buyer


This gem is a "fooler." In reality, the gentle wedge and razor sharp leading edge makes for controlled separation of glued seams. What was a purchase on a "whim," has become a reliable tool.

Excellent repair tool

By

Verified Buyer


This tool does everything it is supposed to and makes hitherto tense jobs surprisingly easy. I first used it to separate the veneers on the resonator of an all-wood banjo I was restoring.


The angle ground on the blade acts as a gentle wedge when separating glue joints but doesn't allow the edge to dig into the wood or wander. Used cold or with a little applied heat it allowed me to tackle most separation jobs with increased confidence.

Great tool

By

Verified Buyer


Great tool. First time I used it was to remove head veneer on a warped neck. Did such a great job I was able to reuse original veneer.

Shoe Knife

By

Verified Buyer


Yes, I said shoe knife. I worked in a pattern shop for Chrysler in the 80's and these were handy little knifes we used to fillet and shave Styrofoam. I could not find them until I saw them at stew mac. They have a thin, flexible blade that sharpens easy and is nice for opening cracks and slicing grain repair wood.
