DP Gyutou - 9.4" (24cm)

I’m assuming a commercial kitchen grade where they would want something bigger than 210mm, which pretty much doesn’t exist in a Japanese Wa-handle within your budget. Here are two just over your budget Kagayaki VG10 Ebony Kagayaki VG10 240mm Maybe consider Yo-handle options Tojiro DP Gyuto

This is extremely niche to myself, but a handle heavy knife was really bad for me in sushi. I have my setup where I keep my water to my right, for hand and my knife. I sort of just quickly tilt the knife into the water and out, really fast but I bought a Tojiro DP Gyuto and the balance, while superb

Great budget for a first Japanese Gyuto — right in the sweet spot where performance and aesthetics both start getting genuinely impressive. At £100-160 in the UK you have three solid options depending on what matters most: If performance is the priority — MAC Professional Gyuto 210mm (~£110-130) Pro

For solid and affordable knives, look at Tojiro, Takayuki, and MAC. All you need initially is a Gyuto (210mm or 240mm), and you can survive with a cheap paring knife/petty for awhile - victorinox paring knives are super affordable. This in 210mm or 240mm might be ideal: https://japaneseknifecompany.
