Blake, 24, joins the Nomads from United Counties League Premier Division North side Newark and Sherwood.
Last season, the former Mansfield Town youth striker scored 22 goals in 48 appearances and will be hoping to utilise his goalscoring threat for the newly promoted NPL side.
Blake is well versed at Step 3 and 4 from his time at the likes of Alfreton Town, Matlock Town, Frickley Athletic, Belper Town, Carlton United, Hyde United, Gainsborough Trinity, Hyde United and Gainsborough Trinity.
On his move to the Nomads, he said: "From what I played against last season, there's no reason why Anstey can't get promoted again.
"It felt like I was playing against a family, not a team, and that's something I'd love to be a part of.
"It's time to kick on, score goals and get that league title."
