מוּמָר לְאֶחָד מִשְּׁאָר עֲבֵרוֹת, אֵין צָרִיךְ לִבְדֹּק לוֹ סַכִּין, וּלְהָרַמְבַּ”ם צָרִיךְ. וְדַוְקָא בְּמוּמָר לַעֲבֵרָה, אֲבָל מִי שֶׁהוּא פָּסוּל לְעֵדוּת בַּעֲבֵרָה
מֵעֲבֵרוֹת שֶׁל תּוֹרָה, אֵין צָרִיךְ לִבְדֹּק לוֹ סַכִּין, אֲפִלּוּ לְהָרַמְבַּ”ם

An apostate who continues committing the same transgression, we don’t need to check his knife, according to the Rambam it needs to be checked, specifically if he is an apostate because of a transgression, however if he is an invalidated witness by a transgression that make up the torahs list of transgressions, you don’t need to check the knife, even according to the Rambam.
