My Stop Saw worked flawlessly

Filed under: Uncategorized — Stephen Shepherd @ 3:23 pm

Today when I was using my saw, the inherent feature worked as advertised. The moment the first saw tooth came in contact with my knuckle, I stopped sawing in a terra-second, as near as I can tell.



  1. A “terasecond” would be 10^12 seconds or nearly 31,700 years. You may have meant “picosecond” which is 10^-12 seconds or maybe “terrorsecond” which is the second during which you experience absolute terror that you’ve done something permanently damaging.

  3. Last time, mine didn’t. My handsaw took quite a chunk out of the tip of my thumb & the nail. Then again, the same thing on the table-saw would mean I wouldn’t have a thumb!

  4. Whoa,
    I have been planning to replace my saw with a Sawstop. I have cut myself twice in 35 years, luckily only superficial injuries each time though I do have a 35 year old scar.
    Maybe it is time to take the plunge and buy the new saw. Which model do you have?

    By the by, love your book. I am going to write about it on my blog soon.

  5. Just to clarify for everyone, Stephen is speaking of his soon-to-be patented Knuckle-Stop. Stephen realized the problem with flesh contacting saws was not the saw, it was the physical attraction between saw teeth and knuckles, a well documented problem as noted in MedLine. I can’t go into details, but generally speaking, the Knuckle-Stop consists of a metallic object that intersects the saw at that very moment saw would touch flesh, halting the progress of the saw and thus saving the extremity. At the present time, the Knuckle-Stop is only licensed for use with Disston Hand Saws.

  8. Stephen! It’s Abdullah at The Beer Nut. Glad to hear you didn’t cut your finger’s off! Is that knuckle-stop mass manufactured in china? (chuckle) Just wanted to let you know that we have lots of isinglass in down here, may the fish glue flow! Drop by some time, even if just to chat old time tech! Cheers!

  9. OK, everyone, that was a joke, a play on words, I do not own a Saw Stop Table Saw, I don’t own any power tools. I am alright and will be more careful in my posts.

  10. Glad yours is working mine appears to be broken. I took a good nick out of the tip of pointer the other day at work. I will blame it on the foreign, Japanese, toothed saw. My good old Disston would have never cut me on the back stroke setting the kerf. Of course the look on the customers face when I whipped out a handsaw to break down their lumber was priceless as was the look as I bleed all over the floor.
