Delrin Toolmaking Workshop. NBSS, Boston, October 4-5, 2025

Some tools you can make in this workshop, or design your own.


Making Delrin Tools by Hand for Bookbinders and Conservators. Register here!


This is a rare chance to take a two day Delrin toolmaking workshop. Anyone who needs small hand tools for manipulating, delaminating, spreading adhesive, etc. is welcome. Making tools is engaging, fun, and practical. Delrin is an excellent material for many bookbinding and conservation tools, such as folders, lifting tools, microspatulas, hera, and creasing tools. We will work together designing, roughing out and finishing of several tools. Working Delrin is a meditative activity, no previous experience required. Safe, low dust methods of working Delrin will be emphasized. This workshop is a great opportunity to geek out with other tool lovers. After the workshop you will have some useful new tools, and possess the know-how to alter, maintain, and make more variants. Warning: tool making is highly addictive. 

North Bennett Street School, Boston Mass. October 4-5 2025. Register here!

New Tool! Deluxe Delrin Spatula

DELUXE DELRIN SPATULA

Last month I taught a toolmaking class at the University of Cincinnati, and Ashleigh Ferguson — rare book and paper conservator and Co-lab manager — made a beautiful “Griffin” spatula which I coveted. Rather than steal her tool, I developed my own version. Her tool helped me reexamine some long-held negative opinions about double ended tools.

This Deluxe Delrin Spatula is an ideal hand tool for conservators in almost any discipline. Useful for pressure sensitive tape removal, delaminating, paint and emulsion consolidation, applying adhesive under detached layers, controlled pressing, excess adhesive removal, working under magnification, and more.

The thin tip — due to the wedge shape in the thickness — is great for applying minute amounts of adhesive. The flexible wide tip (see below) can direct pressure downward, and be used with a twisting motion to help pry off unwanted layers.

SMALL TIP. THE DOTS ARE ABOUT 1MM APART
LARGE TIP, ABOUT .15 MM THICK AT THE EDGE

Delrin has a similar coefficient of friction as teflon, but is more abrasion resistant. Black delrin is harder than white delrin, likely due to the carbon, and stays sharp longer. The octagonal handle shape is comfortable in a writing or drawing hand position, and won’t roll off your work surface. Comes with a two stage sharpening kit and instructions to resharpen. The handle may feel familiar to some: it is the same diameter as a Rotring 600 mechanical pencil.

Black Delrin, octagonal handle, approximately 200mm x 8mm. Both tips are slightly flexible, with the small one about 1-2mm wide and blunt. The large tip is straight with sharp round corners, and about .15mm thick at the end.

Purchase here!

Or if you would like to make your own version, join us for a week-long toolmaking workshop at Emory University, October 7 – 11, 2024.

FREE UPCOMING EVENT! Live Q&A during a screening of “The Craft of Leather Paring”, Saturday Jan. 13, 12:00, noon, EST.

On Saturday at noon, I will answer questions live during the premier.

In November 2022, I performed virtually for The American Bookbinders Museum, demonstrating the hand paring of leather. I discuss the reasons for paring, show some historic paring examples, then demonstrate in detail the techniques and thought processes that paring leather involves. And of course I talk about the tools, using an M2 hybrid knife to demonstrate.

In a collaboration between myself, The American Bookbinders Museum, and Darryn & Carrie of DAS Bookbinding, the recording of this event has been edited to provide a concise overview of the subject that Arthur W. Johnson describes as “one of the most admired skills in bookbinding”. Video link, or sign up for a notification to watch. 

During the presentation, I preform a bookbinders’ party trick of seeing how many sides of leather I can edge pare in a single strip. Any guesses? I hope to chat with some of you Saturday. Bring lots of questions!

Stropping is an easy way to keep your knife super sharp. Preparation and use are demonstrated.

Thank you Darryn for the edits!
