For many years I have used very successfully a falkniven DC4 around £20 or less a good base to start and believe me once you get the feel of how to use it properly it will deliver, recently because I wanted something even better I invested in a work sharp WSGSS (not just as cheap but buy once cry once comes to mind here) and am very impressed it's like a DC4 but much much more it still requires a certain skil from the user but its very easy to master honestly I think you would like it around £60 and has an upgrade kit around £40 to make it even more versatile and will last you a lifetime just my tuppence worth and most definitely worth a look.
