45 Year History  -- Made in USA --

 

U.S. Patent 10,661,596 - The invention relates to providing hand held engravers that can hold a graver closer to parallel to the work while at the same time raising the handle away from the work.   The invention is also reversible allowing a graver to be held at a steep angle to the work.

Benefits of the new angled engravers, collets and extensions

Background of Patent 10,661,596, and Pending Patent:  The traditional hand engraving tool which has been used for banknote and deeper engraving has been in existence for centuries. It consists of a graver (also known as a tool point, tool tip or graver) inset into a mushroom shaped handle that is made to fit into the human hand.  The engraving artist pushes the tool tip through the metal.  Ideally for this manual engraver, the lower and closer to parallel the graver shank can be held to the work, the better.  A help to manual push engraving of the past was the use of a bent graver shank.  

A bent graver shank allowed the front portion of the graver shank to be held close to parallel to the surface and yet allowed for the handle to be up and away from the work surface which provided clearance for the operator's hand.  In more recent times, carbide has been utilized for gravers rather than carbon steel gravers.  Unfortunately, carbide shanks cannot be bent as steel can be.

Thus, there is a need for powered and manual engraving tools that can hold a graver shank at an angle from the tool's body, and allow the straight graver shank to be used closer to parallel to the surface being engraved.  This provides the benefit of the past bent steel graver shanks, as well as giving raised clearance for the operator's hand on the handle.  There is also a need for the opposite, that is, to have the graver shank held to a steep angle to the surface being engraved, for various work operations by the artist such as bulino, inside ring engraving and hard to access concave surfaces. 

In more recent times power hand engravers have come in existence.  The invention is an improvement for removable collets to be angled in order to hold the graver shank at an angle and thereby give the benefit of what the bent graver shanks of the past provided.  It is also an improvement that the removable nose collets are reversible to allow the user of the tool to rotate the insert so that the angled graver shank will be held at a steep angle to the work for various operations such as bulino, inside ring engraving and hard to access concave surfaces.

The above photo illustrates a low angle of attack and a high angle of attack to the work surface with the angled engraver invention.

 

We take intellectual property seriously

Each of our angled gravers, angled collets and angled extensions are marked with the patent number and patent pending. This provides potential infringers constructive notice of our patent rights, which means that in a patent infringement lawsuit, damages can be awarded for infringement that took place before the lawsuit was filed or the infringer was given actual notice of the infringement, such as, a warning letter. In other words, the longer the infringement, the greater the damages an infringer can be assessed.

Potential infringers should also be aware that in cases of willful infringement, a court may increase the damages up to three times. A court may also order a permanent injunction. Link - More information about intellectual property infringement.

Infringers will typically argue that the invention was already known but this line of argument is very difficult to support. Quote from An insight on the US Patent system by Michael Artemis "Correspondingly, although someone may claim to have seen what they consider the same invention years ago, if the alleged prior invention was not documented or publicly available, it may not qualify as prior art with respect to the invention. When the Patent Office issues a patent, it is cloaked with a VERY powerful presumption of validity."

If you should see someone or a company copying the angled graver technology on the internet or social media, you may copy and post this notice and a link to AngledGraver.com. Thank you for understanding.

Reversing Angled PalmGraver®

The PalmGraver® can be configure to have a low angle of attack, or a high angle of attack to the work.  See video to the left how to switch it back and forth by reversing.  The tool hole in the nose is .133" in diameter.  So 3/32" square graver shanks fit as well as 1/8" round, or any size that will fit in the .133" hole.

Manual Push Reversing AngleGraver
Includes wrench,
$79

(Does not include graver point)

 

Benefits of high angle of attack:
*Clearance and hand comfort
* Bulino dots and dashes.
* Extra heel clearance for less drag.
* Inside ring engraving. 
* Hard to otherwise access concave surfaces.
*Improved viewing when using the microscope while stippling and while gold inlaying.

Benefits of low angle of attack:
*Clearance and hand comfort
* Line engraving, partially with manual push engraving.

 

AngleCollet

The handpieces picture in the photo are the BenchJewel at the top and a collet nosed burl handle PalmControl.  The bottom two handpieces in the photo are foot controlled collet nosed Classics with AngleCollet that is rotated opposite to illustrate a high angle of attack and low angle of attack.  Two adapters are also in the photo which are used on long collets.

Similar to the reversing manual Angled PalmGraver these collets are angled and are reversible.  With the AngleCollet the handle does not need to be reversed to switch from low angle to high angle of attack.  In order to change between the two modes pull out the AngleCollet, rotate and reinsert it. 

Reversing AngleCollets are available with and without offset.

The clearance created with the angled graver steep is great for  hard to access concave surfaces.  For example here is the engraving in the bottom of a spoon by Marius Mellebye.  A place that is notoriously difficult area to get to.  The AngledGraver together with the "Extra High Angle" ground point is able to get in to engrave it.

Most of the V templates that have a uniform parallel heel can be utilized for a bulio template by simply not placing the heel on it which is done with V part of the large template.  Link to template page So skip that step while sharpening and it will make point dig right in for making a dot or dash.  Information about bulino can be found at EngravingSchool.com.
