Skjerpene ligger ca. 500 m nord for gården Rekå. Det er skjerpet i området i perioden 1880-1900. Hovedskjerpet består av to vannfylte synker som ligger 15 m fra hverandre. De har vegger på 4x3 mm og 4x1 m. Foliert amfibolitt (74º/80º) med uregelmessige kvarts-epidot årer/linser er vanlig. Kvartsganger som er 2-6 cm brede og har randsone av grovkornet amfibol forekommer også. To mineraliseringstyper er observert. Svak disseminasjon av bornitt+kobberglans i amfibolitt og strenger og disseminasjon av pyritt i grovkornet amfibol i randsona til kvartsåre. Mineraliseringene er imidlertid ubetydelige og området har ingen økonomisk interesse. |

Ett par bitte små skjerp finnes i dette området. En liten forsenkning med en mindre tipp og små hauger indikerer dette. Kun steiner av kvarts uten sulfid ble påvist. |
