BALL POINT MINI KNIFE

Recommended Posts

MAKE YOUR OWN MINI TRIM KNIFE USING RECYCLE USED CUTTER BLADES

 

We all need sometime or another a super sharp mini knife, well here it is..
I don alot of small cutting and always needing to remove a spur or the inside of a capital A will not get a complete cut so I made this handy and portable mini knife.
 

build one and I'm sure you will find many uses for this fine tool it is also handy ball point to hand to your wife to sign the back of that brand new  charge card..

 

everybody has a drawer full of ball point pens that hasn't worked in years so grab one take it apart and get an old roland style blade. you will notice that when you pull the brass end off of the nylon ink tube that after you push the blade past the swollen end it fits quite snug ( I put a small drop of super glue on the end anyway ).
 

make sure that when you push blade into ink tube to keep it the same length as the brass ball point end so it will have the propper length of blade exposed and it can retract correctly..

I hope you will find this as handy as I do.
enjoy, signmaker

Nice "Tip" (pun intended) Also noted that proper blade depth is important even in this instance. Ha ha! I'm going to have to try making one of these.

I'm surprised you didn't notice that the big dog is heat transfer vinyl..

it needed more than a trim or two... in needed to be mirrored..

oh well , thank goodness it was only 20 cuts instead of 100 before

I caught the mistake.. you know I'm supposed to be a sigmaker

LOL....it happens to all of us.

 

I didn't notice your "oops...

just thought it was already masked with clear tape...

but a closer look confirms the MIRROR IMAGE BUG

gotcha!

 

Love the pen idea!

I missed that! Hate it when that happens. I have gotten into the habit of saving my HTV cut files mirrored so they are already correct. Saves my bacon fairly often.

I like your thinking :) You could extend this idea towards a vinyl air release tool (to poke fine holes in vinyl that has air trapped from a bad application) using a pin. Go look at the 3M ones - they are insanely expensive. Like $60+

 

But I haven't come up with a better pin adapter (part that accepts the pin into the pen to keep it snug enough) than the pin through a pencil eraser end trimmed to fit the spent ink tube. I suppose a hot glue gun would work too...hmmm.

 

I was able to find an Aliexpress seller though who basically sells these types of pin pens for $8.95 US shipped. Mine just arrived in Canada. This is a screen capture from their ad. Opening it up and looking at what they've done, it's simply an empty pen cartridge with a "professionally" manufactured metal nib that contains a pin head. You could easily make something like this yourself but I chose to buy it for I didn't have to get covered in ink. You can even buy the empty pen/pin head refills on Aliexpress too should you damage the pin head.

 

It's good quality and comes in a nice black cardboard box. I think it's worth the purchase. I've attached a picture of what I received taken apart to show it's simplicity - just like a normal pen but with a pin head on the ink cartridge.

Get one of those 2-color pens and have both tools in one pen.

 

Combining it all into this type of level pen of course. THEN we're talking...

 

I like the hexagon shape so it doesn't easily roll off your "whatever".

I'm waiting on the BannerJohn special edition custom wood turned version with a cutter blade tip . . . very very exclusive if they come to market!
