Scribe-Master KWJ600 Tradesman Kitchen Worktop Jig
Fast, accurate Mason’s Mitre joints — aligned from the front edge

Stop wasting time measuring from the back of the worktop and second-guessing your layout. The Scribe-Master KWJ600 is built for kitchen fitters who want repeatable, accurate joints with a simpler setup.

SightLine Front-Edge Alignment (Patent-Pending)

Our SightLine window lets you align the jig from the front edge of the worktop — where you can actually see your marks clearly.
Mark → Align → Clamp → Cut.
Less measuring. Fewer mistakes. Faster installs.

Clean Mason’s Mitre joints in minutes

The KWJ600 is designed to route full male and female Mason’s Mitre joints quickly and accurately, helping you move from first cut to fit-up faster on site.

Built for real jobsite conditions

Unlike MDF templates that can swell or wear at the edges over time, the KWJ600 is CNC-machined from High Pressure Laminate (HPL) — chosen for its rigidity, moisture resistance and durability under repeated router use.

Compatible with common worktop materials

Suitable for use on:

• Laminate/chipboard worktops

• Compact laminate

• Composite worktops

• Solid timber worktops

How it works (simple 1-2-3)

1. Mark your cut line with a square

2. Align the mark using the SightLine window

3. Clamp and cut — job done
