`
`1.
`
`A die responsive to a pressure applied thereto to cut a shape from a sheet material against
`
`whichthe die is pressed, said die comprising an inside opening that corresponds to the shape to-
`
`be cut from the sheet material, an outside border that surrounds said inside opening, and a cutting
`
`edge that projects from said outside border to cut the shape from the sheet matenal, said cutting
`
`edge being located on said outer border such that said cutting edge surrounds the inside opening
`
`of said die, whereby none ofsaid outside border extends past the cutting edge and noneofsaid
`outside border lics betweensaid cutting edge and said inside opening, so that said cutting edge is
`
`registered with the shape to be cut whensaid die is positioned on the sheet material and the
`
`outside border of said die surroundsthe shape.
`
`2.
`
`The die recited in Claim 1, wherein the cutting edge which projects from the outside
`
`border of said die is a cutting blade.
`
`3.
`
`The die recited in Claim 1, wherein said cutting edge is located on the outside border of
`
`said die so as to hie exactly at the periphery of the inside opening of said die surrounded by said
`
`outside border, whereby said cutting edge exactly defines the shape to be cut from the sheet
`
`material.
`
`4,
`
`The die recited in Claim |, wherein the cutting edge of said die is located at the interface
`
`of said inside opening with said outside border.

`
`
`
`5.
`
`Thedie recited in Claim 1, wherein the outside border of said die has a width of at least
`
`2.5mm.
`
`6.
`
`A methodfor cutting a shape from a sheet material comprising thestepsof.
`
`printing the shapeto be cut on the sheet material;
`
`forming atleast a first die having an inside opening that correspondsto the shape to be
`
`cut from the sheet material, an outside border that surrounds said inside opening, and a cutting
`
`edge that projects from said outside borderto cut the shape from the sheet material;
`
`locating said cutting edge on the outside border of said die suchthat said cutting edge
`
`surrounds the inside opening of said die, whereby none of said outside border extends past the
`
`cutting edge and none of said outside border lics betweensaid cutting edge and said inside
`
`opening;
`
`positioning said die on the sheet material so that the outside border ofsaid die surrounds
`
`- the shape printed on the sheet material, so that the cutting edge of said die is registered with the
`
`shape; and
`applying a force to said die for pushing said cutting edge thereof through the sheet
`
`material to cut the shape outwardly therefrom.
`
`7.
`
`The method recited in Claim 6, comprising the additional step of locating said cutting
`
`edge on the outside borderof said first dic so that said cutting edgelies exactly at the periphery
`
`of the inside opening of said die surrounded bysaid outside border, wherebysaid cutting edge is
`
`automatically registered with the shape printed on and to be cut from the sheet material.

`
`
`
`8.
`
`The method recited in Claim 6, comprising the additional step of locating the cutting
`
`edge of said first die at the interface of said inside opening withthe outside border ofsaid die so
`
`that said cutting edge corresponds exactly with the shape printed on the sheet material.
`
`9.
`
`The method recited in Claim. 6, comprising the additional step of forming said first die
`
`such that said outside border thereof has a width of at least 2.5 mm.
`
`10.
`
`The method recited in Claim 6, comprising the additional step of applying said forceto
`
`said first die to push said cutting edge through the sheet material by meansofa die press.
`
`11.|The methodrecitéd in Claim 6, comprising the additional step of forming saidfirst die by
`
`means of chemically etching a flat piece of metal.
`
`12.
`
`The method recited in Claim 11, comprising the additional step of forming at least a
`
`second die by means of chemically etching the flat piece of metal, such that the second die is
`
`nested within and spaced from the first die so as to lie at the inside opening of said first die,
`
`wherebythe size of the inside opening of said first die is larger than the size of the inside
`
`opening of said seconddie.
