Adam Savage Builds a Magic Prop Knife!

Adam builds a prop knife worthy for a magician friend that, unlike every knife he's seen previously as magic props, is actually worthy of stage presence. Its particular shape and dimensionality is inspired by iconic dive knives, making this a fun replica machining project. Adam also gives a primer on precision hole-cutting machine tools at his disposal, and why the annular cutter is the perfect tool for this job. Just keep an eye on that murder foil!

I will admit, when I saw the title, I thought it was going to be some kind of trick knife where the blade somehow retracts despite all the holes in the handle, but just a big solid hunk of aluminum turning into a knife is still really cool lol

[JamesWjRose]

"murder foil" Great name, and your excitement at showing us the differences in the drill bits, just awesome. Thank you for sharing all of this.

[PearlJamk]

This is such an Adam thing to suddenly start elaborating not 1, not 2 and not 3 but FOUR different drill bits while completely off subject essentially.

[scottnj]

Adam the best part of sharing your shop time is, ... all of us tool nerds are so with your enthusiasm. Regardless of the build.

I haven't heard a more satisfying power on/activation sound than the mill being activated at 5:31. Every time he uses it in a video, I wish things in my everyday life had such a distinct and visceral activation signal as that sound.

[LoganLovell]

I love the chaotic nature baked into every video of Adam making something. I feel right at home

[sstockemer]

I love it when Adam explains the cutting edges of drill bits. :)

[kstAs]

I just fcking love Adam man, when he is excited, i get excited when he is happy, i am happy. What a beautiful human being.

[NorwayRoy]

Thanks! Yet another nice one!. I have HEARD so many of youur videos. I tend to do a lot of tinkering and making stuff while listenig to youur videos and only look up when you are exited about something 😀 Today i added some small cooling fan to the amp on a PA speaker to prevent an annoying whining noise when it get hot sometimes. Might need to change the amp chip aome day but, this will do as a patch for now 🙂

[Fliegenpilzkonsument]

I love that you go out of your way to teach us things. Continue being awesome.

[bitdog]

Drop at the end and the face is priceless.

I think all families need a Adam.Anything need to be made or fixed we just take it to Uncle Adam.It amazes me every time what Adam does.From model making to everything else.Absolute Genius!

[markschmitz]

Sir, your enthusiasm for things is infectious. I also imagine that you just have a box of those plugs somewhere just in case you need a greebly or embellishment on a prop build.

[winzmuc]

It's so great to watch You building interesting things. Since my Dad (who btw was good in building stuff, too) died three weeks ago I'm in a depressed mood these days. But Your calm and still entertaining kind cheers me up. Thanks a lot!

[rybec]

I love that you talked about the mill bit. I saw the inside surface of the hole and the really nice clean edge, and I was _very_ impressed. And then explaining how you achieved that in a single plunge was just the icing on the cake. Such beautiful, clean work. I could see that on an "oddly satisfying" video, despite the fact that I don't find it odd at all how satisfying that is to watch!

[stephenkohler]

I love the noise the drill press makes getting up to speed and the little hint of it when it stops. It sounds incredibly well made

[christopherjunkins]

Coming back to this, after him talking about hole saws and how to get a precise hole... I see that wobble now! OMG, I never thought... but yea, steel bends... way more than you'd think... watching him put the drill bit to the side of the blade and how it just creates that illusion of a see-through edge... my goodness.

[blackdra]

Thanks Mr. Savage. Your shop class is alway informative and fun

To get the chamfers in the holes equal bring the quill down to the hard stop then bring up the knee until you get the chamfer you want then release the quill then just use the quill down to the stop on each subsequent hole to achieve the same apparent chamfer on them.
