Recently Updated!! Better contour, jimping, and more ALL AT NO EXTRA CHARGE! ;c)

Note: Metal blade compatability coming soon, as well as a no-hardware option! Legacy files available for a limited time.

This is a simple print that allows you to buy cheap Sawzall blades and cut with them by hand. It's remarkably fast at cutting if you choose the right blade - I recommend finer-tooth blades like the one pictured. Two machine screws and nuts are required, and a 2nd hole must be drilled into the blade for a 2nd handle anchor point. The handle works best with 9" blades in a recessed, full-tang format. Extra long or shorter blades can be a little harder to work with. The nuts and bolt heads are recessed into the handle for extra comfort. There are many different screw and nut combinations that can work with this handle, but I used hex nuts that are 5/16" from flat side to flat side, and a pan-head screw with a 7mm OD head and 3/8" long. Thread type doesn't matter as long as your nuts and bolts match up, obviously. This was a fairly quick build and can certainly be improved, so feel free to do so. I wanted a minimalistic saw in my tool belt for the times I need to trim up a poor circular saw cut or something. I've not used it for that yet, but have cut many limbs down on a couple of pear trees that needed pruned up. Supports in the hex nut cavity make printing easier and more likely to be successful, but most printers can probably bridge that span without supports. Alternatively, you could print it with the flat narrow side down, or you can also experiment with pausing the print at the appropriate height and placing the correct sized nut into the hole and printing over it in place. I tried this but failed to modify my gcode correctly the first time and haven't attempted again.

Push in your hex nuts, mark and drill out your 2nd hole in the sawblade, then screw it all together.

cool goinig to use this as a handle for a knife i am making out of a sawzall blade

For all of the people trying to figure out what size screws to buy at the hardware store -- I just went and bought a few different sizes. The generic hardware store #6-32 pan-head machine screws/nuts fit perfectly.

Appreciate it, thanks!

Ur welcome. I do a lot of woodworking and that saw handle will be a great help. the hot end of my printer is usually jammed but as soon as i can get it fixed i will print that

No protection against sliding off and cutting your fingers open. Your design is thoughtless and a hazard of security for everyone that makes it. Fix it!

In the future please either concern yourself about proper security about your device or do not create anything you wound not give your 5 year old.

Thank you!

Are you serious, most utility knives doesn't have "protection". This is a tool not intended to be handed to 5 year olds. If you don't have the common sense to use a hand saw without cutting yourself then you shouldn't be using any tools at all! Why do you think everything designed on here should be able to be handed to a 5 year old to play with? SMH

1st: Most knifes DO offer that kind of protection with only the exception of pocket knifes. Pocket knifes don't because they have to fit in a pocket which makes this hard to implement.

2nd: A saw does WAY more tissue damage then a knife and is therefore is more dangerous to work with.

3rd: What has having common sense to do with slipping and cutting yourself because you have sweaty fingers? Are you saying that people with common sense don't make mistakes?

There is a principle in engineering called "make it hard to make mistakes" because mistakes happen. That's why bridges have barriers. That's why the contacts of power plugs that carry electricity are lowered in instead of showing out. That's why microwaves don't turn on when they are open!

Well bridges have barriers and and vehicles have still flipped over them and you can still get electrocuted by power plugs if your "sweaty fingers" slip and touch the contacts. That doesn't mean these things should be taken away from the public.

Sure you cant completely stop accidents from happening but you can minimize the risk by with good engineering. Sorry that i am so angry. I hope you see my point

I just care about security

It's a simple design that is far better than using a bare blade in hand (which I have done myself on more than one occasion).

Don't like it? Don't use it. Better yet - design your own that you feel is safe. This isn't some kindergarten playground and you aren't the safety police.

I've seen people past child age making mistakes. I have seen very smart people injuring them badly by mistake. That's why you design stuff in a way to prevent mistakes.

No i don't like the design and i will not print it but I think its highly irresponsible of this guy to design tools that lack of common safety features. People get injured because of that!

LOL, thanks for the comment. I have the freedom to design it as I wish, just as you have the freedom to not make it if you dislike my design. I have cut many limbs without ever injuring myself. If you require a guard to further protect your or your child's fingers, you have several options: 1) buy one from the store, 2) make the effort to design your own remix, or 3) take advantage of the excellent remix options already available, like this excellent one from juancarlospaco - https://www.thingiverse.com/thing:2341728

Maybe i have written a bit to harsh but please consider this: Its just a question of numbers. If enough people will download this design a some will cut them by accident. They will remain with a nasty wound disabling there arm for weeks. If they are really unlucky it may even never fully heal.

Do you want this to people who choose your design to happen? If not just design your tools in a way that makes it hard to make mistakes.

It does not have anything to do with being careless or stupid. Accidents happen.

I have to step in here. How would some one using a hand tool get a "... nasty wound disabling there arm for weeks..."? If your cutting near you arm then you should put the tool down and step back. Figure out a way to do it differently.

Great job on the simplistic design. Going to make tonight.

Thanks for sharing. Saves me from designing and publishing myself! Printing now.

Well, apparently the Diablo blade I have is different than the one pictured here. Same length (9") but the blade I have is for metal cutting only and is a bit wider than the blade you used. I will design a handle to fit this style blade and post up a revision asap/ Pics etc later!

edit: maybe I will pick up one of these style blade so my Handi-Saw print does not go wasted. I might actually have a couple wood cutting blades a tad shorter in length that should fit.

be warned. one of these pieces is upside down. rough side out. make sure to rotate if you want smooth side out. otherwise, EXCELLENT.

The "Handi-Saw" branded side is up to reduce the chance of a print failure when not using support material in the screw holes - the best orientation for printing without supports however is probably on the narrow side opposite the finger groves. Thanks for taking the time to report feedback, and I'm glad it worked out for you!

This worked out very nicely. I trimmed and drilled it for nuts and a saw blade I had lying around, and I recommend this to anyone thinking about it.

Great idea!!!! This is one of the reasons for having a 3D printer and why I love to look at all the new things people design and make. So simple but oh, so elegant! I will be making a few of these, for sure. Thank you for sharing.

You know, it takes more effort than I'd like to publish designs like this, so I really appreciate your feedback.
