This one is fun.

I do like the finned/sashimi sword but as usual it may be avoided?

Code:

. 5 .|. 3 .|2 . 9
3 . .|9 8 .|. . .
. 9 1|6 . .|. . .
-----+-----+-----
6 . 2|. . .|. 9 .
4 . 7|. . .|6 . 5
. 3 .|. . .|7 . 1
-----+-----+-----
. . .|. . 9|5 7 .
. . .|. 1 6|. . 2
9 . 3|. 7 .|. 1 .

with an invitation like that for an alternative solution path, I couldn't resist.
notice the UR on {4,6} in r27c23
the 8 in r7c3 and the 7 in r2c2 are strongly linked.

Code:

.------------------------.------------------------.------------------------.
|*78 5 4-8 | 147 3 147 | 2 6 9 |
| 3 U467 U46 | 9 8 2 | 1 5 47 |
| 2 9 1 | 6 45 457 | 348 348 3478 |
:------------------------+------------------------+------------------------:
| 6 18 2 | 14578 45 134578 | 348 9 348 |
| 4 18 7 | 128 9 138 | 6 238 5 |
| 5 3 9 | 248 6 48 | 7 248 1 |
:------------------------+------------------------+------------------------:
| 1 U46 U468 | 348 2 9 | 5 7 348 |
| 78 47 5 | 348 1 6 | 9 348 2 |
| 9 2 3 | 458 7 458 | 48 1 6 |
'------------------------'------------------------'------------------------'

UR46[(8)r7c3 = (7)r2c2] - (7=8)r1c1; r1c3 <> 8
for a one stepper.
