Replaceable Blade Craft/Marking Knife Kits | The International Association of Penturners

Accurate layout is the key to a successful project. And using a quality marking knife is a much more accurate way to mark a line than with a pencil. This is especially so when laying out joints that require. RIGHT The knife scores an extremely fine line, so unlike a thick pencil line, you know exactly where you need to cut.

I like Japanese-style marking knives similar to the ones you see pictured above. The blades have right or left beveled edges and steep angles, giving them a really sharp point perfect for accuracy. However, one drawback is that they dont come with handles, so theyre awkward to hold onto. To solve this problem, I made handles to give me better control when I use them. If you take a look at the drawing below, you can see how the handle goes together.

The blade is sandwiched between two wood blanks. The copper rings, or ferrules, on the ends not only help hold it together, but give the project the look of a traditional Japanese woodworking tool. Set Screw. One nice feature is the set screw that holds the blade in the handle. It grips the blade firmly, yet allows you to easily change blades or remove the blade for sharpening. In addition, you can flip the blade around and slide the beveled end of the blade into the handle when youre not using the knife.

Getting Started. It may seem strange to start off with square blanks when the handle is going to end up round but thats exactly how this project begins. Youll start with two rectangular blanks one for each half of the handle, as you can see illustrated in Figure 1.

After cutting the blanks to size, youre ready to rout a groove into each half to create a marking knife ferrule 60 for the blade Figure 1a. When the grooves marking knife ferrule 60 done, hold the pieces together and slide the blade into the slot for a test fit. You want it to fit snugly, but not so tightly that you have to force the blade into the slot. Once youre satisfied with the fit, its a good time to drill and tap a hole for the set screw in one of the rectangular blanks, as shown in Figure 1b.

After the screw hole is drilled, you can glue the halves of the handle together, taking care not to get any glue in the groove. Round the Edges. When the glue dried, I took the handle over to my router table and rounded the edges to create a circular body. The box at the bottom of the page shows how I did this. After that, I cut the square ends off the blank, as you can see in Figure 2, and plugged the hole in one end of the blank End View.

Thats all there is to shaping the handle. On the next two pages, a few finishing touches are added to dress it up and make it easier to hold. But turning the square blank into a smooth, round handle isnt difficult at all. As you can see in the drawing on the right, the rounded handle is formed in the middle of the long rectangular blank. By doing marking knife ferrule 60 this way, the square ends make the blank easier and safer to work with.

First, mark the starting and ending points on the blank. Then, set up a 38"-radius roundover bit and the router fence according to the inset drawing on the right. To rout the blank, slowly pivot the blank into the bit at the first mark and slide it to the second mark.

Repeat this three more times, rotating the blank each time. Once the sharp corners are gone, you simply cut off the square ends to complete the handle.

Burning tung oil onto the copper ferrules results in this black finish. Ferrules are used on many woodworking tools such as marking knives and chisels to prevent the handles from splitting near the blade.

But theres no denying that they can add a nice look as well just take a look at the photo at left. The ferrules I marking knife ferrule 60 were simply 1 " x 3 " copper 2 8 bushings that you can pick up at any hardware store, as shown in the inset photo at right.

Planing the Facets A perfectly round knife handle didnt feel quite right, so I added facets and a barrel shape to the handle. This gives you a better grip, plus the knife isnt as likely to roll off your workbench. And, best of all, because these facets are randomly planed into the handle, you cant really mess them up. The photo on the right shows how the facets are made.

First, draw a line around the center of the handle this will be your reference point for both directions. Then, using a block plane, work from the centerline and shave the handle. Start with light pressure and increase it as you near the end. What youre looking for is a tapered effect. After a couple of strokes, roll the handle and shave some more Marking Knife Ferrule Group off. When youve finished marking knife ferrule 60 end, flip the handle over and taper the opposite end of the handle.

Be sure, however, not to cut into the tenons on the ends of the handle. Once thats done, take a chisel and create a chamfered shoulder around the tenons. And finally, install the ferrules on the tenons and spray the handle with marking knife ferrule 60 coats of lacquer. Starting from the center, taper the handle toward both ends using a block plane to create a faceted, barrel shape. To make the jig, all you need is a scrap of 2x4 and a piece of 18" hardboard.

Start by ripping a 6"long piece of 2x4 down to " wide. Turn it on edge, and then drill a 34" hole near one end of the block, centered on its width. After the hole is drilled, glue the hardboard onto the block as marking knife ferrule 60 base for the jig.

Next, install a 38" straight bit in the router table. Place the block against the router table fence and adjust the fence so the bit is centered on the end of the block. Raise the Marking Knife Ferrule Quotes bit to 18" above the table and push the block from right to left until the bit cuts marking knife ferrule 60 into the side of the 3 " hole.
