Rake
Old English raca, racu, of Germanic origin; related to Dutch raak and German Rechen, from a base meaning ‘heap up’; the verb is partly from Old Norse raka ‘to scrape, shave’.
wiktionary
From Middle English rake[and other forms], from Old English raca, racu, ræce(“tool with a row of pointed teeth, rake”), [1] from Proto-Germanic *rakō, *rekô(“tool with a row of pointed teeth, rake”), from Proto-Indo-European *h₃reǵ-(“to straighten, right oneself”).
The verb is partly derived [3] [4] from rake(“tool with a row of pointed teeth”) (see etymology 1) and from Middle English raken(“to rake; to gather by raking; to rake away (debris); to cover with something; (figurative) to conceal, hide; to destroy”)[and other forms], [5] from Old Norse raka(“to scrape”), from Proto-Germanic *raką, probably ultimately from Proto-Indo-European *h₃reǵ-(“to straighten, right oneself”).
From Middle English rake, rakke(“pass, path, track; type of fencing thrust; pasture land (?)”), [7] and then partly: [8]
The verb is derived from Middle English raken(“to go, proceed; to move quickly, hasten, rush; to roam, wander”)[and other forms], from Old English racian(“to go forward, move, run; to hasten; to take a course or direction; to control, direct, govern, rule”), [9] from Proto-Germanic *rakōną(“to take a course or direction; to run”), from Proto-Indo-European *h₃reǵ-(“to straighten; to direct oneself”).
The origin of the verb is uncertain. [12] The noun is probably derived from the verb. [13]
The noun is a clipping of rakehell(“(archaic) lewd or wanton person, debauchee, rake”), [14] from to rake (out) hell (“to search through hell thoroughly”), in the sense of a person so evil or immoral that they cannot be found in hell even after an extensive search: see rake(“to search through (thoroughly)”).
The verb is derived from the noun. [15]
etymonline
rake (n.1)
"toothed tool for drawing or scraping things together," Old English raca "rake," earlier ræce, from Proto-Germanic *rak- "gather, heap up" (source also of Old Norse reka "spade, shovel," Old High German rehho, German Rechen "a rake," Gothic rikan "to heap up, collect"), from PIE root *reg- "move in a straight line," with derivatives meaning "to direct in a straight line," thus "to lead, rule" (source also of Greek oregein "to reach, stretch out," Latin regere "direct, rule; keep straight, guide"). The implement is so called perhaps via its action, or via the notion of "implement with straight pieces of wood" [Watkins].
rake (n.2)
"debauchee, libertine; idle, dissolute person; one who goes about in search of vicious pleasure," 1650s, shortening of rakehell. Hogarth's "Rake's Progress" engravings were published in 1735. Generally of men but also used by 1712 of women of similar character.
