When they stopped supplying replacement blades in the small paper fold-up inside the plastic sleeve, they went to the little black "dispenser box", but I cannot recall what year. Seems like it was early 70s. 
Maybe if you bought a lot. I got 5pack blades in the paper n cardboard folder til at least 1975 at home.When they stopped supplying replacement blades in the small paper fold-up inside the plastic sleeve, they went to the little black "dispenser box", but I cannot recall what year.

That’s the first one I’ve ever seen. Guess I need to read more vintage XActo literature. NiceIs the wood handle older than the metal ones?
Fixed it for you.I found this earlyiest box recently...
I know (think?) you were mainly joking, but I would personally find it very uncomfortable being such a small, elevated platform. When I am working with mine, or any similar kind of precise cutting or even measuring and marking, I have to have everything - backing, work object or material, tools, as well as and especially my arms and hands - laid out flat and on the same surface. Just thinking about the edges of the box with no place to flatten my arm out is making my right hand unstable.It looks like the box top makes a good backer when cutting. I'll try to remember that.
Unless he had the box turned 180*....the angle of the cuts suggests the previous owner may have been left handed
I would suspect so, but like RTM, I'd have to go back to the same Google Books ads I found to date the first gen stuff.Is the wood handle older than the metal ones

First Welcome; 50 yrs experience = lot to share!
It has the logo.Does the handle actually have an X-Acto name on it?
Thanks for that; days not worth living if you don't learn something new!Train Thek has referred to the mechanism as "the closer". With that information and a close look at the pictures, it is obvious to me that the lever at the top cams and pulls the collet up against a taper to grip the blade. So the mechanism is just a quick release for blades. A very interesting handle.
Does the handle actually have an X-Acto name on it?
Agree on the odd & seemingly unnecessary & complicated to manufacture change to the blade lock; if aint broke for 50yrs, don't do anything to it - have always like to give the knurl a little extra 'feel better' twist myself - may be a company president's son-in-law deal. (OSHA?)Now that Stubby pointed it out, I see that the knurled part is not screwed on, it's uniform with that handle. Frankly, I am not sure why they felt the need to monkey with a chuck that had worked well for decades (it doesn't take that long to twist it on or off to tighten and loosen and change blades), and with that logo and that blocky all-caps branding style, I know it's fairly modern, but I looked through every catalog I have and every catalog on IA/ITCL, anyway, all of which are older than 1972, and couldn't find anything like this handle and its mechanism.
@Burgerboy who hasn't been here since 2022 was more of a modern collector. If he ever drops back in and catches up, maybe he'll have some information on it.
This might be the patent for your blade cover. Granted 1986Does anyone know what decade this knife was made? The original head is below. I just put a fresh head on it bc I still use it. It was gifted to me in an old tool box with a bunch of other old tools. Haven't been able to find another one with that type of logo stamped into the aluminum like that. Thanks!
Here is a fairly recent patent for a similar lever to release the collet.Now, a few days ago, picked up an unknown X-acto knife that -based on my knowledge- doesn't exist. It's a standard hobby knife with nice light blue anodized body, split collet, but the closer... It's a lever at the back. Did anybody see one like that?

Burnishing down tape? We had some tape we used for fat lines. Tape looked like this.Appears to be a #1 handle with a roller (possibly a bearing) at the end of the handle. Any idea of age or purpose of the roller.
Thank you RTM! This is exactly the knife I have. Later today I'm going to take it apart and post pictures. My theory is, the knife was proven very good, but too expensive to produce, therefore not marketable. Years later X-acto simplified the concept that lead to the development of the GripsterHere is a fairly recent patent for a similar lever to release the collet.

That should not be taken as any kind of indication of its non-production. I only looked in X-Acto catalogs, and only those published prior to 1972 and available on IA/ITCL. I have little to no interest in digging any deeper than that to explore this knife (or any X-Acto knife, or generally, any tool) past that era.Private Lugnutz unable to uncover another;
I see that the patent was assigned to CBS, Inc., NY, NY. In 1981 it was assigned to Hunt X-Acto, Inc., with a Philly address. I never had any interest in the evolution of the ownership of the original company formed by the original inventor, Sundel Doniger (formally, X-Acto Crescent Products Company, Incorporated, 440 Fourth Avenue, New York, NY), and in this case, I don't think I want to know, but who/whatever Hunt X-Acto is with respect to the original, it looks like the design didn't come from in-house. They acquired it....also found this one from 1976, which I think is your tool.
That is interesting. Thanks for researching that one![/url]Here is a 1966-67 catalog I don’t see in ITCL
@rustyzman
Your sliding blade covers are listed as new in this catalog.
So much for my 80s theory.
And a different 1950s than at ITCL
Correction. There was an acquisition involved, but the design did come from in-house after all!...it looks like the design didn't come from in-house. They acquired it.
) The purchase was part of a larger diversification effort by the media company in that era. The Hunt Manufacturing Company purchased X-Acto from CBS in 1981, when the diversification was reversed, which is when the patent was reassigned. As long as I am at it..., Elmer's (yes, the glue company) purchased Hunt (and the X-Acto brand) in 2003. Newell Rubbermaid acquired Elmer's (and the X-Acto brand) in 2015.
