I designed and manufactured three sample patent pending proto type Metperial multi tools for the Kickstarter project to a high quality, heavy duty and compact that suits a key ring survival accessory, or a multi-function tool that has a titanium clip to latch on shirt or pants pocket for EDC.
Manufactured from 440c stainless steel that is EDM wire cut from plate then CNC machined and heat treated to a hardness of 56 HRC.
A stretch goal is available if the funds raised are over $20.000 AUD with a choice to upgrade to CPM S35 VN stainless steel for an extra $20 AUD add on, the high quality expensive 1/4" CPM S35 VN flat bar needs to be imported from the USA.
Attachments can be added on each end of the Metperial multi-tool such as the wood chisel end has a titanium pocket clip with a titanium bolt fixture that acts like a simple door latch for the attachment to lock in place, also the attachment has a flat screw driver and a combination 5mm + 3/16" nut wrench, on the other end the attachment has a 3mm and 2.5mm Allen key with a 4mm nut size wrench, it has a small spring to simply latch the attachment in place.
Theses attachments guard sharp parts like the chisel, the attachments allow a striking area on both ends such as the wood chisel for carving.
The rewards are to be airmailed in time for Christmas gifts that are suited for male and female, the patent pending multi-tool is supplied in a compact gift box for a possible WOW response from a loved one, employees, customers or friends appreciation gift that comes with or with out attachments for any one that does not need the extra multi function accessory's.
The Metperial multi-tool has a smooth ratcheting motion for up to 10mm and 3/8” nuts; however another stretch goal is offered if funds raised are over $40.000 AUD to offer larger sized open end ratcheting wrench attachments including ring spanners for $12 AUD each that also have a hole specially designed to fit onto a titanium split key ring .
The precision EDM wire cutter allows exact fitting for an assortment of attachments, such as screw drivers, allen keys, crow bar for leveraging nails, strap wrench, podgy bar, hammer, cold chisels, wood chisels, chipping hammer, knife blade, saw blades, pulleys, carbineers, cutlery, flint to start fire,sling shot etc.

23 = Hole for split key ring
24 = Centre punch, window breaker, scriber for fabrication marking, self-defense short sharp shock to distract and escape an intruder.
25 = Finger nail file, traction for gripping, striker surface for flint to make fire.
26 = Groves so bottom lever part does not slip of edge of paint can and evenly opens lid so no damage, small rasp and scraper.
27 = bottle opener, fits on top edge of beer can so chisel part punches a vent hole on top side of can.
28 = Titanium pocket clip, small leaver, flat screw driver.
29 = Ruler metric on one side and inches on the other.
30 = May have assortment of attachments, such ratcheting wrench and ring spanner sizes , screw drivers, allen keys, crow bar for leveraging nails, strap wrench, podgy bar, hammer, cold chisels, wood chisels, chipping hammer, knife blade, saw blades, pulleys, carbineers, cutlery, flint to start fire, sling shot etc.
The Metperial multi tool clip is manufactured from grade 5 titanium including the bolt fixture that is to be further developed with more attractive design with added functions, making a fashionable design statement, especially if the stretch goal is made with a further choice to up grade to CPM S35 VN stainless.
The Metperail multi tool has been designed so a 1/4“polishing stone fits in the channel part to act as a sideways guide.
A new shape blade is redesigned when manufacture for a longer lasting cutting edge that will have a small stone guide supplied with stone to suit the end angle for precisions sharping.
Titanium Gr 5 spring clips are available if add an extra $10 AUD = $8USD to your pledge for any sized Titanium spring clip and titanium split key ring.
The full set of 3 titanium Gr 5 spring clips and titanium split key rings are available if add an extra $25 AUD = 20 USD to your pledge.
Titanium Gr 5 spring clips sizes are 42mm, 32mm and 25mm, the split key rings are 18mm, 25mm and 32mm
To make sure the right reward is chosen the list with pictures below explains more clearly.
Qin is the CNC workshop foreman who assisted to help me CAD draw the multi tool designs then organized the CNC machining, Qin also laser embedded the ruler measurements into the multi tool.
Lee is owner operator of 8 EDM wire cutters with outstanding quality and service.
Below is He and I, is a close friend for ten years that has helped me with past Cad drawings, EDM and CNC machining with my other multi-tool inventions as the one displayed on YouTube https://www.youtube.com/watch?v=E3-EsetvqRg that is also waiting to be manufactured with a complete new design when financed to do so on a kickstarter project in the near future.
He has also allowed me to use his past workshop to develop boat inventions, also EDM and the CNC machining the titanium tools shown on several pages below that have attachments on my early proto types.
He assist me with this kickstarter project for develop and end manufacture, to know his many friends and their high quality circle of machining shops and other sources allows personal hands all QC at all times, most of all a bond of friendships which is part of the Chinese industry culture.
The work shop He and I are pictured is where I develop the proto type Metperial multi tool and are to CNC machine Kickstarter backers rewards, this is high quality, professional and reliable company, with a work force that is incredibly skilled, yet humble and kind, the owner of this work shop resembles the same.
I invite kickstarter backers to join and give a helping hand on this journey that I will share step by step with updates and pictures of the complete manufacture including titanium manufacturing and will do my utmost best to make this is worth your while and memorable.
Below I am organizing the jig to CNC machine the Philips screw driver on the early proto type Metperial multi tool in He,s workshop.
During that same time I experimented on several larger prototype versions of titanium multi tool attachments.
Risks and challenges
EDM wire cutting and CNC machining procedures are time costly for each multi-tool; EDM wire cutting is several times more expensive than laser or water cutting method; however EDM is needed for precision manufacture of the multi-tool and its precise matching attachments including the nail file fine teeth and smooth surface finishes in areas that are not able to be polished.
There are 6 procedures each side of the multi tool for the CNC machining, again time consuming with the biggest challenge is to be able to manufacture at a viable end cost to be acceptable to Kick Starter sponsors while at the same time providing outstanding quality.
The cost of travel and accommodation to QC every moment of manufacturing, including heat treatment HRC hardening, supervision while sharpening each blade, laser embedding the measurements, then arranging gift boxes and other accessories to maintain superior quality at all times is no small task and costly.
I need to design the titanium clip further into a more attractive design with more tool functions also the center knife blade is to be redesigned to the best shape cutting knife possible.
There are no early bird specials and have made the lowest possible price for all rewards and have stretch goals for over $20.000 AUD which sponsors can upgrade for $20 AUD to CPM S35 VN stainless, imported from the USA that is the best material possible, also other stretch goals such as a variety of attachments if rewards reach $40.000.
Surprise gift rewards are offered if the manufacturing numbers are many, this cuts the manufacture cost and would happily to share this benefits with sponsors.
The delivery time should have no problems as the EDM wire cutter workshop has 8 EDM machines that can work 24 hours each day, also I have other reliable and good quality EDM workshops as back up.
The CNC machining takes a large amount of time to produce a high quality multi tool, I have other CNC machine workshops readied just in case for back up if any delay to make sure sponsors can rely on Christmas gifts in time.
