The bevel cutting tool for hand building and clay tile artists

AccuAngle close up The AccuAngle is a one-step cutting and beveling tool for clay artists. No matter the level of your hand building skills, AccuAngle can help you increase the quality of your work while making the job easier and quicker. With 11 preset angles you can create basic geometric shapes from the 3-sided equilateral triangle to the 12-sided dodecagon. This bevel edge cutter has a 90-degree angle included for squaring edges.

The AccuAngle ruler is scaled in inches and includes a convenient centering scale.
AccuAngle slider and needle toolComes in 2 sizes : 16" or 32".
We also offer the replacement slider !
The AccuAngle is designed to use with any long needle tool. The holes in the sliding cutter are preset at specific angles. The lowest hole #3 cuts a 30 degree angle. See the list below for other angle options.

With the ruler resting on top of the clay slab insert the sliding cutter into the ruler. Position the sliding cutter just beyond the edge of the slab. Placing the AccuAngle Insert the needle tool into the desired angle hole and allow the tip of the AccuAngle Clay Cutting tool to rest lightly on the cutting surface. AccuAngle with needle tool inserted Grasp the cutting slider at either end using the thumb and index finger. Pull the cutting slider toward you. (If the slider does not pull easily then lift the needle tool slightly so that the tip of the needle does not dig into the cutting surface)
Pulling the AccuAngle slider
The resulting bevel cut is clean and straight. Cutting with the AccuAngle
Finished clay surfaceBevels can be cut from the finished /exterior side of the clay slab or from the unfinished / interior side.
AccuAngle also makes it possible to cut beveled openings on the interior of a clay slab. Beveled opening in clay slab With the help of a heavy paper or cardboard template AccuAngle can cut beveled curves on the interior or the outside edges of a slab. The sliding cutter is removed from the ruler and placed on the surface of the template. Insert the needle tool at the desired angle. Keep the needle tool pulled tight to the edge of the template and pull along the template edge. Picture Picture The AccuAngle makes reinforcing seams easy. Opposing 45 degree angles creates a perfect 90 degree reinforcing strip for the rectangular corner. (see below) Picture
One of my favorite uses of the AccuAngle is to create blind seams by cutting partial bevels on the unfinished side of the clay. This allows me to make a folded seam without disturbing the textured surface on the finished side of the slab.
First I cut a 90 degree along the base. Picture
The next step is setting up the needle tool so that it only cuts about two thirds of the way through the slab. This can be done by using a piece of tape as a "stop" to limit how far the needle tool extends from the sliding cutter. An eight of an inch slice from a wine bottle cork is also a good stop material and more easily adjustable than tape. Picture Picture Picture
Flip the textured slab over and define the vertical seams of the object. Cut a "v" groove centered on the seam line by cutting bevels in both directions. In the photo below 30 degree angles were cut on either side of the seam line. Picture
The "v" grooves are scored, brushed with slip and the slab is folded. This leaves the textured surface in tact with little or no touch up from stretching. Picture The finished product. Picture #3 - 30 degree angle creates an equilateral triangle
#4 - 45 degree angle creates a rectangle
#5 - 54 degree angle creates a pentagon
#6 - 60 degree angle creates a hexagon
#7 - 64.2 degree angle creates a heptagon
#8 - 67.5 degree angle creates an octagon
#9 - 70 degree angle creates a nonagon
#10 - 72 degree angle creates a decagon
#11 - 73.6 degree angle creates hendecagon
#12 - 75 degree angle creates a dodecagon
