Problem: how to install frets easily in the hard-to-clamp area over the neck heel. Solution: Jaws3!

Developed by our own Al Rorick, this ingenious fret press clamps onto the fingerboard and utilizes the same 2-1/2" radiused brass inserts as our other Jaws tools. Fret seating takes place at the end of the tool, letting you reach those "impossible" frets. Works for entire necks, too!

Jaws3 is a professional fretting tool that includes five interchangeable 2-1/2" brass inserts, grooved to fit over the fretwire crown. The inserts match popular fretwire radii: 7-1/4", 9-1/2", 12" and 16", and a special 6"-radius insert holds down the fret ends for gluing. Additional radii are available.

3-point thumbscrews seat the fret perfectly, and the rigid extruded aluminum body ensures stability. Jaws3 includes an adjustable neck clamp, radiused wooden neck caul with an ingenious internal magnet for fumble-free setup, and an angled wooden body caul for "set-neck" solidbodies and acoustic guitars.

Why press frets? Pressing the frets can save time and produce more consistent results. That's why it's the method that's widely used in guitar production. Pressed-in frets are less likely to have loose ends and uneven heights, because there's none of the recoil produced by hammer blows.

All Jaws fret presses are designed to work with our grooved brass fret press inserts. The inserts fit over the fretwire and are interchangeable to match popular fretwire radii. More from the Jaws collection:

If your fretboard is level you end up with a perfectly fretted instrument that save endless hours levelling and re-crowning frets

Good Idea but poor design!

I agree with the other reviewers, to me... wasted space in my tool box. Of the 6 times I have used it I have had to redo frets every time. Maybe Stewmac could have incorporated the Jaws2 press seeing the bar clamp is the same, would be more reasonable then.

The one tool I sent back.

I bought one of these a while ago (before the rating system). I couldn't get a single fret seated properly with it. I ended up spending about an hour trying to make this tool work the way it's supposed to and decided to ditch it and just hammer the frets in. I will say that SM is awesome about returns. They had no issue taking it back. I've been thinking about getting one of the other Jaws tools, but this one just doesn't seem to want to work unless the slots are quite loose, at least looser than I like to work with.

Great tool but you must be careful

I bought a j-3 when it first came out. Almost immediately I screwed the middle screw down too far and ruined the retaining ball bearing. S.M. folks are such great people - they sent me a new one immediately - no charge. After not needing to use the tool for several months (I have all their other fretting tools, J1,J2, fret press, and hammers - and use them regularly) I forgot about the bearing and once again broke it. My own fault. No excuses this time. I do think the plastic knobs for pressing down the brass inserts are weak (metal or a different type would be nice) - I cracked one tightening it. So all in all - The tool has it's uses, but YOU also have to know it's limitations. Like many of S.M.'s tools, it's meant to be used by professional, trained luthiers - not wood workers who think they are guitar "builders". I applaud S.M. for all their recent "training" videos as it has expanded their market place and helped many a player. I am a big S.M. supporter and have many/most of their tools. I am glad I bought this tool. Sometimes it's just what you need to get the job done. Time is money. Just wish they sold replacement bearings/parts for forgetful people like me. :)

Important: "Works for entire necks, too!" DOES NOT MEAN that it works good. This tool uses standard stewmac aluminium radius-block as a base - and this base still has 7,25" radii! On fingerboards flatter than 7,25" - 99% of all fingerboards - you can easily damage recently installed frets while clamping jaws3 to the neck. Of course i tried to use some soft material as a padding between fretboard and jaws3 base, but there was another problem: now the central pressure screw can't reach as deep as needed (padding adds some height). And more: If you accidentally move central screw too deep, the insert holding ball will be broken. And now the screws. Seriously, they are really hard to turn when pressing fret into the slot. This tool is a weak - ordinary fret press (or drill press with radius insert) will be much stronger. Actually I archived better results even when pressing fret with one big red clamp (through jaws3, of course). I'm totally disappoint.
