My Journey To The Perfect Drag Knife

[walter67]

So following on from my last post, whilst using the Drag knife to cut out some cardboard box templates I noticed the blade was starting to dull, so time to order
some new ones.

Once they arrived I tried fitting one, but to my surprise the Stanley blade would not fit
I paired up both my old blade & the new one only to notice that the Stanley logo and the dimensions had changed, I then got in touch with Stanley tools and asked if they had made any alterations to there blades, and they confirmed they had. Gutted!

This meant I would need to get out the Dremmel to modify the insert, I was not confident in doing this for making it totally unusable, so I decided I would
buy some more aluminium stock and make a new one plus I could make a 2nd
but smaller profile drag knife for more intricate cuts..

Now here's the mad thing, I was looking for a pen to write down my new dimensions
and picked up a sharpie from my draw only to find it had dried out, I then had another
rummage and found another one but noticed this was double ended, a thin and fat tip
a either end, then all of a sudden I had a light bulb moment, then after many countless
failed attempts at making prototypes this is the result…
