DIY pick handles from recycled HDPE

When it comes down to it there is nothing better than manual tools for your Lock pick Set, whether they be retail, homebrew, macgyver style. DIY'ers look here.

There should be no negative effects on a hacksaw blade.

Thanks for the info. I might have to give it a try.

I just think it's ironic how it has "high density" in its name, but floats in water and is only slightly denser than LDPE. :)

Please let me know how it worked out. ;).

Ok. So I gave it a try today.
I tried all sorts of plastics.

Now first I need to add... My picks are made from Bobby pins.
I came across a few problems.
When the plastic melts, then my pick falls through the melted plastic. So I end up with plastic on the top and my pick on the bottom. Then I tried melting the plastic in a big goopy ball, like the video, and shaping it around the pick. Actually worked out OK.

So I tried all sorts of plastics that I had lying around the house. Some worked and some didn't. Some just shrunk down in size and became super hard. Some melted and lost its shape all together. Some became brittle, some were all rubbery and soft.

I guess what I'm trying to say is, if you want to, play around with some plastics you have lying around at home and you'll come right..

As for myself, I prefer smaller handles. I just put one or two heat shrinking wire insulators and Im as happy as can be. You have more feeling of what your pick is going through during the job. It's more like fishing. One can feel each little nibble.

So, the plastic thing works. Depending on the type of plastic and heat, all you need is a few minutes to make a few handles. But I will not be doing it again.

Ps, I see what you meant about wanting to use clips during during the melting process. I tried it. The clip was too strong and when the plastic becomes hot, the clip down more bad than good. I lay a flat pice of metal over the plastic before melting in the oven, that stopped the plastic from curling up and deforming too much.

Thanks for your feedback.
Most people use flat materials like hacksaws or feeler gauges instead of bobby pins, so they shouldn't end up at the bottom. :)

It will take some time until I can start another attempt. First I need the clamps and then some more HDPE. We don't have plastic milk jugs where I live (the color is boring anyway) and we don't use up a cleaner or shampoo bottle that often. Seems that I have to dive into some garbage bins. :lol:
I plan to do all 7 picks at once, put them between 2 metal plates and 8 sheets of plastic (+ baking paper), clamp the whole package and then heat it.

Just as a precaution to anyone who reads this thread you shouldn't just go around your house and get some plastic and try to melt it in the oven. Make sure the plastic you use is specifically HDPE. Do a google search to find out if the plastic you want to use is HDPE or not and if you're not sure don't use it. Some types of plastics can give off toxic fumes when heated or burned that would be bad to breathe in. HDPE doesn't give off toxic fumes when heated and that's why you see people using it for making various things. Sorry for being a buzz kill I just want to make sure people know that it can be dangerous if you don't know what you are doing.

That's absolutely right. I neglected to mention that I always experiment in a well ventilated area with the necessary safety equipment. Safety is always important. Thanks for the comment PowerHaus930. I don't think it's a buzz kill. But let's not give anyone the impression that trying new ways of doing something is a no-no. That's how a lot of us started lock picking. We wanted to try something new. Something that some would consider to be a no-no. Experiment. Learn something new. So, by all means, if you have an old broken plastic lunch box that is not HDPE, try it out, you may just find some material that is just right for you.

I think picking is the same. Try all the picks on the market and find which one suits you best. There is no right and wrong.

With all that said. Taking precautions like safety, whether it's for health or legitimacy or any other reason, always do your best to protect yourself.

P.S i found that my lunch box lid worked the best. I have no idea what type of plastic it was as there was no markings on it. It was a soft rubbery floppy lid.

Anyways, please take all precautions possible, even if it says HDPE. You never know, it may be a lie. And it may even be a case that 10 years down the line, they discover that HDPE is hazardous to your health too.

Second attempt:

I put them between 2 metal plates this time. Doesn't look too impressive yet, but I'm very pleased how it came out. The picks seem to sit perfectly in the middle.
The HDPE bent slightly after cooling down, but let's see if that's still the case after removing all the exceeding plastic. Otherwise I'll fix that with a hot air gun.
From what I can tell by now this is extremely tough stuff. I'll need a jigsaw and a maybe router to cut and shape it... but not today...

P.S. I'd have liked some really crazy colors, but the blue stuff was all I got. :)

I must say, that does look nice. Have fun carving it out. I'd like to see the finished product.

impressive work bembel, that cleaned up real nice! Can you heat it up and press a logo or name into them?

How far does the metal go inside the handle? and is it a special shape or do you have holes in the shank so that the metal tip does not easily pull out of the handle over time?

Yes, you could do a logo, I'd press something hot into it.
The pick blade goes maybe 5cm or 2 inches into the plastic.
There are no holes, but I have absolutely no concerns that it might come out. But you could also work in some dents with a file.

If you try it out let us know how you like it.


Forgot to report. ;)
Yes, it's soft and flexible when you have a thin bottle or lid. But when it becomes thicker, it's not so soft and flexible anymore. Imagine a cutting board (which are often made of HDPE). They're really tough and not easy to cut. (I tried cutting the molten HDPE with a knife but gave up really quick) :lol:
I finished it with a 400 grit and I even like the way it feels. It's absolutely worth giving it a try.

I am wondering is you could use this oven baking method with HDPE using a 3D printed mould.

The only think is I am not familiar with the types and properties of plastic 3D printers use.
If I would guess, I am pretty shire there is a possibility.
