The kidney removal of Catherine Eddowes.

We are talking 1888 here, surely the organs would have just been ripped out when the animal was slaughtered and hung upside I dont think it would take a great deal of skill to do that

In the UK, kosher butchers (also known as shochets) do not require a specific license to slaughter animals for kosher consumption.

Not true Trevor. There was a Board of Shechita that consisted of the 5 Kosher Butchers on Butchers Row and overseen by Rabbi Adler. They took this very seriously in 1888.

The problem with the continuing suggestion that JtR was a shochet is, I believe, that the knife they traditionally used had a flat straight tip. The standard British butcher/slaughterer used a sticking knife, 6 to 8 inches long, and pointed. This is the weapon described by police surgeons as being expertly wielded by the ripper.

Hi Doc..the shochet could do all of it as they taught all of it. The flat knife or chalaf would not have been used and i agree on the sticking knife. The shochet taught other butchers how and why they needed to keep their tools constantly sharp. It was an integral part of the profession and kosher process.
My suggestion is that this butcher was not a shochet but still a kosher butcher.

That said a Shochet has never surfaced in 136 years. The only Kosher Butcher that has so far surfaced is Jacob Levy. He got progressively more psychotic starting in 1886 and upon his release in 1887 was living in humiliation. By 1890 he was readmitted.

Was Levy the Ripper or was it someone like him living in the same area? Are those records still in existence or sitting in an asylum somewhere? Who knows.
