Skjerpet ligger godt gjemt i en liten dal i tett skog om lag 250 m vest for Grytingen og rett vest for enden av traktorvei. Det består av en 6 m lang, 2-3 m bred og inntil 4 m dyp skjæring drevet inn på vestsiden av åsen. Retningen på skjæringen er NØ (ca. 055°) og går på tvers av strøkretningen til bergartene i området som står loddrett og går tilnærmet N-S. Mineralisering består av meget svak pyritt-impregnasjon i en kvarts-sericittskifer, dels anriket i kvartsslirer. Denne skiferen er granatholdig i enkelte partier og amfibolholdig i andre partier. Det er også enkelte dm-tykke soner med grovkornet amfibolittisk skifer.
