Mishnah 1א׳

כָּל הַכֵּלִים יֵשׁ לָהֶם אֲחוֹרַיִם וָתוֹךְ, כְּגוֹן הַכָּרִים וְהַכְּסָתוֹת וְהַשַּׂקִּין וְהַמַּרְצוּפִין, דִּבְרֵי רַבִּי יְהוּדָה. רַבִּי מֵאִיר אוֹמֵר, כֹּל שֶׁיֶּשׁ לוֹ תוֹבְרוֹת, יֶשׁ לוֹ אֲחוֹרַיִם וָתוֹךְ. וְכֹל שֶׁאֵין לוֹ תוֹבְרוֹת, אֵין לוֹ אֲחוֹרַיִם וָתוֹךְ. הַשֻּׁלְחָן וְהַדְּלֻפְקִי, יֵשׁ לָהֶם אֲחוֹרַיִם וָתוֹךְ, דִּבְרֵי רַבִּי יְהוּדָה. רַבִּי מֵאִיר אוֹמֵר, אֵין לָהֶם אֲחוֹרָיִם. וְכֵן טַבְלָא שֶׁאֵין לָהּ לִזְבֵּז:

All vessels have [a distinction, with regard to purity status, between their] outsides and insides, for instance: cushions, and blankets, and sacks, and packing-bags, according to Rabbi Yehuda. Rabbi Meir says: anything which has loops [through which to thread a drawstring] has [such a distinction, with regard to purity status, between its] outsides and insides; but any which does not have loops, does not have [such a distinction between its] outsides and insides. A table and a serving table have [such a distinction between their] outsides and insides, according to Rabbi Yehuda. Rabbi Meir says: they do not have outsides [i.e. they have no such distinction]. And similarly regarding a board that has no rim.

Mishnah 2ב׳

הַמַּרְדֵּעַ יֶשׁ לוֹ אֲחוֹרַיִם וָתוֹךְ, מִשִּׁבְעָה לַחַרְחוּר, מֵאַרְבָּעָה לַדָּרְבָן, דִּבְרֵי רַבִּי יְהוּדָה. רַבִּי מֵאִיר אוֹמֵר, אֵין לָהֶם, לֹא הֻזְכְּרוּ אַרְבָּעָה וְשִׁבְעָה אֶלָּא לַשְּׁיָרִים:

An cattle-prod has [a distinction, with regard to purity status, between its] outsides and insides: the seven [handbreadths] from the spade [attached to the back end of the prod, are considered to be the outside], and the four [handbreadths] from [the pointed end of] the prod [are considered to be the inside], according to Rabbi Yehuda. Rabbi Meir says: they do not have [such a distinction]; the four and the seven were only mentioned for the purposes of remnants [i.e. if it breaks, these are measures of how much must remain in order for it to still be considered an implement, for purity purposes].
