As Papabull stated, a barber hone and an abrasive pasted paddle strop is another viable alternative and probably costs less to start. 2 names in Barber hones that you can trust 1. Apart and 2. Swaty 3 line ( 3 lines of text stamped on the hone). There are many others but those we know very well.

Hopefully others will list other barber hones that they have had success with.
I would mention the Frictionite 00 and the Dubl Duck dry hone but those are expensive.

Hope this helps,
