Abstract
The tile knife apparatus provides a specialized blade particularly useful in tile work, coupled with an ergonomic handle which provides maximum leverage with a comfortable grip and natural alignment with the blade. The apparatus is especially suited to tile spacer removal and adhesive removal. The blades are provided in varied embodiment widths, including 1 millimeter, 3 millimeters, and 5 millimeters. The blade has a flat edge so that prying and scraping are best facilitated, without excessive injury risk to hands or tile. Each feature of the handle works in coordination with the blade features to facilitate natural hand alignment with work to be performed, while ensuring against hand fatigue. The handle enables easy grip and provides gradually coordinated surfaces and rounded convex ends to avoid user fatigue and hand injuries such as blisters and undue callusing. The ergonomic handle provides for ambidextrous use.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
