Reference for Shabbat 17:2
נוֹטֵל אָדָם קֻרְנָס לְפַצֵּעַ בּוֹ אֶת הָאֱגוֹזִים, וְקֻרְדֹּם לַחְתֹּךְ אֶת הַדְּבֵלָה. מְגֵרָה, לִגְרֹר בָּהּ אֶת הַגְּבִינָה. מַגְרֵפָה, לִגְרֹף בָּהּ אֶת הַגְּרוֹגָרוֹת. אֶת הָרַחַת וְאֶת הַמַּזְלֵג, לָתֵת עָלָיו לְקָטָן. אֶת הַכּוּשׁ וְאֶת הַכַּרְכָּר, לִתְחֹב בּוֹ. מַחַט שֶׁל יָד, לִטֹּל בּוֹ אֶת הַקּוֹץ, וְשֶׁל סַקָּאִים, לִפְתֹּחַ בּוֹ אֶת הַדָּלֶת:
A man may take a hammer (on Shabbath) to crack nuts, a hatchet to cut fig-cake [After it is rounded, it is thick and hard, and a hatchet is required to cut it], a saw to slice cheese, a trowel to scoop figs [from the barrel], a winnowing shovel and a pitchfork to serve (food) to a child, a spindle and whorl to stick [into berries and all kinds of soft fruits], a hand-needle to extract a splinter, [it being permitted to do so on Shabbath, just as it is permitted to manipulate an abscess to remove pus, so long as there is no intent to make a mouth for it], and a sack needle to open the door [if one has lost his key.]
